Sorry guys..... I didn't read all of this.... got family stuff tonight... so if you have done this.. great..

Have you verified the ground?

The tan and lt blue wires will only have power on them based on the position of the lever in the car..

Also, pull the two screws out of the resistor and test continuity between the terminals to the dark blue terminal... If you have power going in you should have power coming out so test the resistor and make sure it's good too.
