I have a 1996 Dodge Ram 1500 with power door locks but no RKE module. Can I add a Factory RKE module w/remote(s) from a junker? Where is the RKE harness? Is there a sticky or link with more info on this? I've been through all the "go to the dealer", "buy an aftermarket...", and "get a good wiring diagram", "get a build sheet(which I have)" type links and discussions...but really this can't be brain surgery...these vehicles must have been shipped with a harness connector and simple procedure so the dealer could make a few bucks adding this feature!
