Hi all, I'm struggling a bit fitting an aftermarket radio.

I bought a kit with a fascia plate (fits) and a wiring harness....but the harness is incorrect...I went to a radio install place hoping they could re-wire it but they just told me to get the "correct" harness adapter...

The harness I got (images below) has a white plug that's too big, a small black plug and a loose wire...and the car has a smaller white plug, a yellow one, a black cable (cd changer?) And the aerial cable.

I'm not really sure how to proceed so any inputs or ideas would be really appreciated!
Thanks so much,
Evan

 

White connector contains all the speakers if you have standard audio. It has power and grounds too. Yellow has all other stuff including power antenna. Round black is cd changer and navigation.
Straight foward pinout is not that easily found. But wiring diagram is at the JagRepair I dont think that correct adapter is even made to these cars.

 

Which year is your car, and does it have the Premium Audio?
As above, the wiring diagrams on the JagRepair website are fantastic, and really, I think the best option you'll have is to just cut the wires and join them up manually. Don't bother with the adaptors
