95WhitePrix Posted January 21, 2021 Report Share Posted January 21, 2021 How do I go about installing a aftermarket remote keyless entry system to just lock and unlock the doors on my 1995 Pontiac Grand Prix SE coupe? Can I just wire it up to the power lock switch in the door? What polarity is the lock system triggered by? I can't find any info on this anywhere for these cars.

55trucker Posted January 22, 2021 Report Share Posted January 22, 2021 You'll need to get your hands on a wiring schematic for the vehicle, preferably the factory manual to detail the system characteristics, I take it you're thinking of something like a Viper 1 way entry system?, they usually include their own rough schematic for tapping into the car's harness. 95WhitePrix 1 Quote Link to comment Share on other sites More sharing options...

I think I have figured out exactly what I need to tap into. Now I just need the system to come. Quote Link to comment Share on other sites More sharing options...
55trucker Posted January 22, 2021 Report Share Posted January 22, 2021 This IS '91.......do not know for sure if there were any alterations in the wiring configuration. ess essentially the relay just reverses the current flow thru the door lock motors to command them to open or close. 95WhitePrix 1 Quote Link to comment Share on other sites More sharing options...
