I have a 99 QX4 and I am installing a Pioneer AVIC-D3. I have installed all of my own stereos before, but I have never installed a nav unit. The new deck comes with a pink,light green and purple wire that are supposed to connect to the car speed signal input, the power supply on the parking brake and the reversegear signal input. Does anyone know where they are located or a link to a factory wiring guide. Anyting would help.
Thanks
