R34 25gt Factory Wiring Colour, Help Needed

[khoala]

hey guys, i recently purchased a new headunit to replace my jdm spec double din unit in my r34 25gt. i got the wiring harness guide which shows the different wiring colours of post 1995 nissan vehicles but my factory wiring colours dont correspond. I tried to just match up the wires to where they were located on the pins, but even the factory wires were connected differently to what it says on the harness guide (example, where it says to not use pin H and L, there is a wire connected to those pins). Anyone know whats going on?

its no surprise as there are so many variations in HUs - I got the R34 with Xanavi HU (cd/tv/sat nav) and separate radio cassette combo and found some differences in the speaker wire colours but you can fairly well rely on the connector pin-outs being what is stated even if the colours of some wires vary ... as for spare pins being used obviously points to accessories - you will probably have to do some tracing/testing

in any case as with any instal you should proceed carefully - it should be easy to work out
