hi, just wondering if anyone can help me here

ive got three wires to connect for the boost gauge

they are:

12V ignition

12V lighting and

Ground

now, just wondering which wires i should splice into for all three ???

the car is a ser1 r33 gts-t....im unsure of what wire goes where

if anyone has pics thatd be excellent

thanks

My guess is that the 12V ignition is for the costant light to light up the smoke face. Then when you turn on your lights the 12V lighting (connected to the ciggy light ie, accesories) makes the boost gauge light up even more as it is now dark out side and the constant 12V ignition lighting is not enough.

Just a guess dude, dont take what I say as bible.... Hope this helps.

can someone help me out i have a TIMEX smoked boost gauge with 3 wires

black, yellow, red

the instructions are crap and don't mention which color is for what

i'd assume: Black = ground

Yellow = lighting or ignition

Red = lighting or ignition

can someone help me out how to find out which is which

also what is the best way to connect the pressure hose. there isn't much holding the hose in and it would leak if under a lot of pressure. any ideas on how to fix this?

zip ties :P

and as for the wiring, don't quote me but i *think* that:

red = +12V constant

black = GND

yellow = +12V Accessories

but this could be worng. i have a timex oil temp and the yellow wire for that is the sensor wire from memory :confused: but i'm assumiong that it's a mechanical boost guage?

I think the australian standard is as below. I cant think why your gauge new need const power though? Does it have any memory features?

If its a eletronic boost gauge (ie comes with a MAP sensor) then it should work as follows:

yellow => 12v Accessories

Red => must be to the MAP Sensor

Black => Almost certainly be ground

If that does not work swap the yellow & red wires.

If its a mechanical job then:

yellow => 12v Accessories

Red => must be const (for memory features)

Black => Almost certainly be ground

zip ties :P

and as for the wiring, don't quote me but i *think* that:

red = +12V constant

black = GND

yellow = +12V Accessories

but this could be worng. i have a timex oil temp and the yellow wire for that is the sensor wire from memory :confused: but i'm assumiong that it's a mechanical boost guage?

The Timex gauges don't have memory features. My oil temp guage needed 12V constant from memory and I still have no idea why it needs it?

My best guess says it's this one:

If its a mechanical job then:

yellow => 12v Accessories

Red => must be const (for memory features)

Black => Almost certainly be ground

the guy said it was electrical but i don't fully understand the difference...it still has a place for the pressure tube to go in...so how is that different to mechanical.

i'd assume it has constant power...because it's smoke faced...eg hard to read without a back light.

and the accessorie light is for when it's night time and needs to be brighter i guess.

jsut thought i'd post some pics of the gauge to help out...

wats the difference between mech and electrical btw?

the parts picture shows a nylon tube (white) and small black rubber tube, pressure nozzle, two tiny things that look like /

........................................ /

(ignore the dots)

and also a screw that looks like |_| with a whole in the bottom for the white pressure hose to fit through...

the hose fits bit could be pulled out easily...eg if underpressure.

any ideas

thansk for the replys guys

It might not be mechanical: It sounds to me like the MAP sensor might be in the guage it self (I know it sounds stupid but it fits the facts). This means that you need the tube in the back for the MAP sensor, const power for the MAP sensor (red), acc for the light (yellow) and ground (black).

if it's got a tube to attach a hose then it's mechanical.

:P

As for the pressure hose:

You need a little "nipple" like thing on the end of the hose that goes into the gauge. Then when you do the bolt up it gets a little crushed and forms a seal. Go to autoBarn or some place like that and they will show you what I mean, you can get these parts there too.

Yea, thats them. It looks like your hose is to fat to use them though :{

That yellow wire is const for sure!

Here is another theory, it may be the case that it is setup to be either electrical or mechanical ???

pictures are now up ^^^^

the nipple things aren't the little gold things in the pic with all the parts??

    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
    • I assume clearances were all a-okay?
