A few weeks ago I started searching around on this forum and youtube for info or a video on the installation of an aftermarket keyless entry system that would work well with our vehicles. Couldn't really find anything specific so I jumped in head first today and figured out how to do it. I purchased a Bulldog Security Keyless Entry system for my 75 Chevelle last year and never got it to work correctly. So I got to thinking that it might work on my 87 El Camino since it already incorporates a relay to activate the power door locks. With a little trial and error I figured out how to wire it correctly. Here's a quick video overview of how I did it. Hope this helps someone else with their install.
