R34 Head Unitt Mess.

[RB25DETC33]

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.

Is anyone able to help a fellow skyline owner out with my audio woes?

i dunno if this any use to you but when i installed mine the head unit didnt work without the antenna, so i bought the adaptor (2 pin to 1) and it works now

Finally sorted out the mess. Of the 100 or so plugs in the loom on 2 are used for A/c unit. with the aid of a bodged up 12v test light i have found the sneaky wires causing my troubles.
