G'day All,

I need your help. As with most R33 owners, we face a problem of having an empty din once we pull the stock CD/Tape player and replace it with an aftermarket one.

Well, to overcome this, I have just bought a R32 triple gauges to fill the slot. Now the problem is, how do I get it to work?

Firstly, does anybody have the wiring loom for sale. I would be happy to purchase it. But anyway back to the point, how can I get it working.

Firstly the gauges, there's a volt meter, temperature meter, and a boost gauge. On the back, there is a wiring pattern that has the plugs for the gauges. What I was intending in the absence of the wiring loom, was to solder the wires directly on the board. I have tested this theory using a 9V battery and some wires. I can get the lights to work, as well as the volt meter directly off the 9V battery, and I guess I can copy the same thing off the car battery, but it gets difficult with the temperature, and especially the boost gauge.

When I tested the temperature gauge, with the 9V battery, the gauge just rose to the maximum. Can anybody advise on how I can get a sensor to get this working? Whenever I supply this one with people, albeit 9V, it just rises to the top.

As for the boost gauge, no matter how I wired it up, it would not move. Of interest the +'ve and -'ve terminals of the boost gauge was separate to the rest of the gauges. Can anybody please advise on how I can get this to work.

So yeah, there you go. Please help!!!

Thanks in advance.

Scotty,

The gauges are all electrical gauges, not mechanical (as you can tell :( ).

And to get them working correctly (and reading correctly) you'll need to get hold of the factory sensors - most Nissan dealers can help you with that.

The temp gauge is for oil temp if that helps any.

With the boost gauge, you MIGHT be able to hook that upto your map sensor that the R33 GTS-t's has - but I'm not sure if the voltage range coming from the GTS-t map sensor will be the same that the RB26 would have. How many wires goes into the boost gauge?? 2?? 3??

Did you get the air con head unit to suit as well?? You know how the 3 gauge holder has a bit missing from the top right hand corner?

J

G'day Jay,

Thanks for your detailed and prompt response. Firstly to avoid any confusion, the gauges came from a R32. so it didn't have the corner shaven off. Hence I did not need to get a new climate control. I'm planning to leave the climate control on top, have the 3 gauges in the middle, and to have my HU at the bottom.

Thoughts?

Anyway, when I plugged, the volt meter into the into the battery, it read 9V, so I presume its simply a plug and play type deal into the car battery. So that covers the first one.

Moving on, so Jay, if I ask a Nissan wrecker for a oil temp sensor, can I simply extend the cables and solder them on directly to the gauges?

Now for the boost gauge, please excuse my ignorance, but what is a map sensor, as I have no idea on how to connect to it. I'll try to get my hands on a digital camera, so you can see graphically, but from what I can see, there is are 3 terminals that I cannot account for. (after covering the lights, volt meter and temp meter)

Therefore I'm guessing 3 wires, but am not sure how a boost gauge is usually connected up. Any thoughts?

Thanks again. If anybody has any further insight, please do write.

Thanks!

Ahhh, cool - I didn' realise that the R32 GTR gauges don't have the corner taken out. Good stuff :(

Re: the oil temp sender - when you ask for it from Nissan you'll have to order the one that is from the R32 GTR - just to make sure you get the correct one, as I'm not sure if the R33 GTR ones are the same etc... You'll also need to check where the oil temp sender to tapped into to read the temp of the oil.

It could be tapped into the sump, or even into the mount for the filter - I'm really not sure - hopefully someone on here can help with that one.. But the wires should be fine just to extend.

I'm not totally clued up on electrical gauges, so if anyone can confirm this please do.

I would say that to make a electrical gauge work you would need 2 or 3 wires. One for the earth, one for constant power, and one for the signal. Some may need just earth and a siganl wire (2 wire type)....

As for the volt meter, you just need earth and the signal (that's why the voltage meter is working when you put the 9v battery upto it).

The map sensor is the small black box that sits up in the top drivers side corner of the engine bay. It measures the presure/vacume that's in the manifold and converts that presure/vacume into a voltage and sends that voltage to the boost meter that's on your dash.

The factory map sensor has 3 wires on it (earth, power, and signal), so if we're REALLY lucky the signal wire from the map sensor will be in the same range that the GTR boost gauge is and may work by just extending the wires (hoperfully the output of the map sensor will take the extra - even if very small - load).

If you can take a pic of the gauge cluster and post if up it'd be great.

How many terminals are on the back of the gauge cluster?

If you can post up a pic and detail what you have already found out (what terminals are for the volt meter etc) we can try and work something out.

J

***EDIT - just to throw a spanner in the works, the gauge cluster could use common earths and power for the three meters too !!! we really need to see the back off the meters, or know how many terminals are there :D ***

Jay,

Thank you again for your detailed reply. It's great knowing that there are guys willing to help chumps like me out. :(

I'll try to get hold of a digital camera tonight so that I may post some pics here.

FYI, yes it looks like there is a common ground wire. What are the implications of that? There are I guess 4 distinct sections on the back of the gauge, illumination, volt meter, temp meter and boost gauge.

Whe I tested the Illumination, it had a seperate +'ve and -'ve terminals. But to get the volt and temp meter working, I used the same ground connection, or what the gauge refers to as Ignition.

As for the boost gauge, there is a positive and negative terminal, but there looks like 2 postive ones which I cant explain. I guess, this will make more sense once I post a picture up tonight.

Thanks again!

does anyone know in sydney were i can get this done i just purcahse one on the weekend tell ya the truth my install is a bit bodgggy i would like it to be professionally installed with 2 out 3 guages to work i have the r33 gtst and this guages came out of the gtr33 so i have that little peiece missin also. any recommendation around sydney west area?

G'day Jay,

Sorry its taken me so long to reply. I've only just been able to borrow a digital camera. Anyway, here is the gauge

Anyway, my immediate concern is with the boost gauge. Given where the word was written, I could not determine where the positive connector is.

Illumination is easy, there is a definate +'ve and -'ve terminals. The volt and temp meter use the same ground, (or ignition).

Given that, there are 3 terminals that I cannot account for. They are on the left hand side, that is the 1st, 3rd and 4th one. Please refer to the picture

Hearing your thoughts that the boost gauge requires three connections, has gotten me thinking that the word Boost +'ve was written there deliberately to cover both terminals.

So, what do you think? :)

Thanks again bud!

OK,

I'll give it a go. But without it here in front of me, probing it with a multimeter I'm stabbing in the dark a little, but we'll see how it goes.

From you comments above, it looks like you've got the lights and the volt meter worked out. That just leaves the temp and boost gauges.

You said before that if you hook up the 9v battery to the temp meter it just swings around to full deflection. So I would say that it'll need the oil temp sensor to work.

The oil temp sensor will send a voltage to the meter which varies up and down depending on the temp of the oil, eg. oil temp goes up, sensor detects the increase and relays that increase as a voltage to the meter - the meter then displays the increase by moving the needle up. To do more work on the temp meter you really need the oil temp sensor (from a R32 GTR).

For the boost gauge, it looks like it a 3 wire type. One of the wires is the ignition which looks like it's common on the board, that leaves two more (boost +ve, and boost -ve). The boost -ve one would be earth and the boost +ve would be the signal output from the map sensor.

Without looking at a wiring diagram for a R32 GTR it's a bit hard, but I would say that the earth would be the earth from the map sensor, the other being the siganl output from the map sensor. Some meters (maybe like this one) need the sensor earth and not just the common earth from the body or straight negitive.

I hope this helps, the best thing to do is buy yourself that oil temp sensor from a R32 GTR, and probe around the meters with a mulitmeter.

And if you can get your hands on a wiring diagram for a R32 GTR it would make it much eaiser.

Cheers

Jayson

Hippy, if only you were in Melb, I'd ask you to help me out. That's cool though. It's still definately on the agenda, again with a help of a few friends.

When it gets done, I'll post up a 'how to' guide here.

Bump to an old but gold thread.

Has anyone posted a 'how to' guide yet.

I have a couple of questions -

*Should the volt meter continue to read 12V once the car ignition is switched off?

*Can the aftermarket oil pressure sender still retain the factory oil light?

Any help appreciated.

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
