2001 Lincoln Navigator with an Alpine system, installing an AVIC90BT.

Can you help me to physically locate these wires?

 

Thanks

Speed Sense - gray/black @ cruise control module

The cruise control module is on the driver side fender.

 

the E-brake - lt. green/ red @ the brake itself, consider doing the bypass, or you wont be able to do much in the Nav menu with out parking the car

 

Reverse Wire - black/pink (+pol) @ drivers kick panel, the harness to the rear
