Does anyone have a pinout for a BCM from a 99 GMC 1500? It was a 5.3 auto truck. Trying to start a engine without disabling VATS. This is just my boredom shining through. I want to see if I can do it. But am Unable to find a pinout.

Well I figured it out on my own. I am going to make a write up on it. If anyone wants to know how to do it, post in here.

Thank you! Wish I would have had this sooner... I am just glad I know how to read a wiring diagram. After I did the VATS relearn, it fired right up. All it took was a Light bulb (to take the place of the Key) and a BCM. Still working on the write up.

I know this is an old post, but does anyone have a write up on this?? I would really appreciate it!
