Sourcing Power For Boost Gauge

I read the other threads about this and tried splicing off the parker lights, problem is, the boost gauge stays lit even when the lights are switched to off. I tried all of the wires in that harness, 3 caused it to light up but each time it remains lit when turned off. What do I need to do to fix this?

edit: seems I have mistaken the headlight power for the parker lights, can someone tell me where the parker light circuit is in the r32s? I'm no good with wiring.

Why dont you have it running off the accessories wire from your stereo.

I have all my gauges powered off that. Unless you are mounting your pods on your pillar and have a problem running wires that far, I reckon thats the easiest place to run wires off.

yeah I couldnt find any extra wire that was a small enough diameter to run it that far, so I'm trying to connect it to the lights, I just don't know where the correct circuit is.

Goto bunnings, mitre 10, autobarn, supercheap auto or wherever and buy a 10m roll of small gauge electrical wire for $5. :D

the smallest gauge I could find was still a fair bit bigger than that of the gauge (apexi) and the people I asked said it would probably have too much resistance so I didnt buy any of it, do you think it would still work fine?

And yeah I got a multimeter but before I tried to use that to find a good wire, I connected it to the headlight circuit and it lit up so I thought that was the job done, I just didnt get why the gauge light wouldnt turn off when the headlight switch was off..

Cigarette lighter wires.

best thing for guages, has everything you want... and really easy to get to.

12V positive

Negative

12V Lights on wire

Agreed. Cigarette lighter wires are the easiest ones to use.

If you want the guage light to come on with ur stereo use the accessories wire from the stereo.

If you want the guage light to come on with ur ignition then use ur multi meter to find a wire that is 12v when ignition is on and 0 V when ignition is off.

In the same way if you want it to come on with ur parking lights find the wire in the cigarette lighter that is 0V when off and 12V when parker lights are switched on.

I use wire taps to connect up the wires. I find this the easiest way.

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
