Hey guys, I picked up an R34 4dr for the gf. It was fitted with the satnav unit, but as it never worked the previous owners ripped it out.

My issue is, Im changing the head unit over but the pervious installer made a mess of the wiring, Plugs have been cut off wires cut down, news wires installed etc.

Instead of the messy soldering, I always choose to make up plugs for my units, normally an 8 pin plug (speakers) and a 3 pin plug, GND/12V/IGN.

So the speakers went together ok, but the previous wiring miss led me to believe that the RED was IGN, BLACK was GND and YELLOW was 12V. (These wires along with the speaker wires, I guess were installed to match universal wiring looms for head units)

Nothing responds, checked the fuses both inside and in the engine bay.

Ive just about lost my sh!t looking over the wiring plans as the colours suggested to be the required wires do not seem to be present. Also searched just about every topic in this forum based on Head unit wiring and diagrams.

-Can anybody post up some pics of the wiring in their car?

-Does anybody know what loom the head unit plugs are on, there seem to be two plugs that fit the CD/tapedeck unit, but dont resemble the pin out diagram (one is for the power relay for the XANAVIA HU, which was removed).

NOTE:

- I dont have a multimeter, want to do it without if possible, as these have never been an issue in the past.

- I didnt copy the original wiring as it came apart during removal (twisted wires with no length covered in electrical tape, VERY PROFESSIONAL.......)

Any help would be awesome.

Thanks guys.

Pics to follow of the mess im in.....would feel more comfortable sitting in soiled jocks. haha.

    • Oof. One of my mates has an R34 GT-R that he initially was a "I want to go twins for response and convenience" on his stock 2.6 with Kelford 272 cams, but his friends are pests and were always in his ear about their place being in the bin.   Eventually one of the 2860-5s decided to add it's own input and force his hand, so he conceded and went for a Pulsar 6262G ("G35 900") with T4 0.85 hotside.    Here's an overlay of the results, same cams, same stock bottom end, same boost, same fuel, just from a pretty tidy 2860-5 install to a Pulsar turbo on a 6boost maniifold on BP98.   Worth mentioning here, it may seem like a dead horse thing but the dyno plot doesn't tell the story of how much better it is to drive - transient response has completely changed the car, he used to have flat foot shifting to stop it having to wind up again on gear changes even at >7000rpm... now it builds boost faster than that even short shifting.   It's 100% transformed the car before you even consider how much better it holds on: Pulsar and Garrett aren't the same, but from our experience if you're just looking for a better drive and the ability to make the same or more power I think the divided G30 770 would probably be the smallest I'd go to.
    • Great work Duncan, any events local you will give it a test once all done? 
    • Sweet, yeah hoping stock gears will hold up. May use the transbrake feature on hill climb starts so that will test it.
    • Yeah, the thread is only nearly 20 years old.
    • Been down in Tassie for 2 weeks (a cruise, not a race for once) but spent a little time on her when I got back. I worked out the injector settings in the PowerFC were not correct for nismo 555s, set those to 66% +10ms and added a little air at closed throttle, set the timing (approximately, because it has some weird non 15o cells around idle) and now she starts and idles properly. She purrs like a kitten (ignore the co2 alarm in the background, I did  ) 20250518_171052.mp4 Next step, off for run-in, tuning and alignment!
