Wrecking a '95 Lumina van which has GM's remote for locking/unlocking doors
and control of power side door. What I'd like to do is transfer that to a
Pontiac Transport same year.

Perhaps the Pontiac already has that but I have no remote control for. Would
the VIN indicate if the vehicle came equipped with this option?

What do I look for in the wiring? I would expect it to be similar to a
command start.

TIA
