Then this and the male part of the harness, and the wire diagram for your car should be all you need. Just match the function and color to the correct location on the harness and you good to go.
Hello mr Smooth1
Thank you for your reply.
Maybe we misunderstand each other because of the language difficulties.
I have the wiring diagram for my car, so what i need is the wiring diagram for the new head unit that comes from the US is300. The colour codes i can understand, and i understand that they are from the US is300 head unit, but i don't know which pin of the male plug / head unit i should connect the wiring from my car to.
I would be very interested in getting the plug, you mentioned it earlier, that would fit in the head unit.
Yours sincirely, and i appologize for the inconvenience
Alex
