Hey guys. Pretty simple question. I have a 96 K3500 CCLB & I'm wanting to add keyless entry. Don't want to spend big bucks though on an aftermarket alarm. My buddy has a suburban with factory remotes & it works good for him, so I figured I'd rip a system out of a junkyard car. My question is, what all do I need? I got a RFA module already from a junkyard car, I knew I would need that. Is there anything else I need? Does anybody have a wiring schematic or diagram or pinout of the system? Any help would be appreciated, thanks!

Surprised you never got an answer. It's been over 6 years now. Any luck?
