I'm trying to install remote start in a 2012 Chevy Silverado 1500. I bought an aftermarket unit because although my truck has remote entry it doesn't have RPO code AP8 which allows for a factory unit. Unit is a one-button remote start only unit, no other functions. I would really appreciate a wiring diagram and any advice that will make the process as smooth as possible.

What brand of remote start did you buy? Did you get a bypass piece for the security of the truck. Wiring diagram of the truck can be found here www.bulldogsecurity.com let me know and I'll see what I can do to help you out.

Thanks for the link!

My truck is very basic. Other than power door locks its basically a work truck. No security system. When I found out I couldn't install a factory unit I went with a basic Audiovox Prestige AS9055 one-button cheapo.

Will I need an "interface bypass module" even with such a basic truck and a one-function remote start?

You will need an interface bypass module for your truck. It is used to interface with your vehicles ignition/ starter kill sustem.

You will need some form of bypass for your truck. There are a couple ways of doing the install on this truck. If you are not familiar I would find a reputable shop to do your install. Its not a hard install if you have the right stuff and a bit of knowledge. I would recommend using www.idatalink.com for the bypass. They work great and have excellent tech support if you need it. It can be done with a couple relays, a couple resistors, and an extra key. But its not worth the headache.
