Hey guys,

I would like to put in new bulbs for the dash. And also would like to add in a dash light dimmer. So that I can adjust the brightness of the light. Just want to know what wires I need to attach a potenmeter (sp?) to?

Or let me know what switch/module I can make/solder etc.. to make one.

Thanks

go to dick smith or somewhere like that to get a dimmer. it is the same thing that you would use for a front/rear speaker fader. generally they have 4 (2 in, 2 out) wires on them. you will only need to use 2 (1 in, 1 out) of them. also you will need to find out which wire is the light wire on the back of the dash.

easiest way is with a test light or multimeter. LED test light recommended over bulb test light, but multimeter is best. to find out take the dash out, but leave it plugged in. the switch on the lights and remove 1 plug at a time to narrow down which plug contains the wire. even after you find it check all the others to make sure it isn't multi feed. then it is time to find the wire in the plug. then once you have the wire then add in the dimmer switch. you will probably need to add some wire so that you can positition the switch where you want.

Its called a potensiometer (or pot... dse guys will know what you mean). You'd need a fairly beefy one, 2 watts atleast I'd say and about 500 ohms.

They only have 3 terminals. Its basically two variable resistors, where the middle pin in the common between them and the two outer pins are there inputs. As you turn the knob one resistor will increase resistance and the other will decrease.

You only need to use one of them so the wires need to go between the middle pin and one of the outside pins. Snips either the lights 12v or ground wire and connect them to the pot and that should be it.

hmm reading this has got us pondering, we are replacing the damaged wiring from the car-steal shit

at the moment the clock and the dash doesn't work for lights, are these linked for the dimmer reasons? where can i find a feed to the instrument cluster so i can feed off the park lights at least, the c**ts made a real mess of the loom and im not sure i can find where they were connected originally

      What brakes on R34 GTT(Europe)

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      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.
