2001 remote starter installation

Anybody know what type of power door locks this truck has (positive, negative, etc) ? How about the polarity of the parking lights?

For your truck you are gonna to need a bypass that controls the door locks. Model 457GW. and for the parking lights I believe they are positive.

will not need a bypass for door locks unless its 03 or newer. should be blue and white. dont remember pos or neg parking lights should be pos at light switch.
