BCM Schematic needed

[Jolly Roger]

Looking for a schematic for a BCM on the 07 Tahoe 5.3

hopefully with labeled explanation of each wire for reach plug.
Anyone have such a thing?

I don't have a schematic but I can tell you a lot of things (almost all) are serial controlled so one wire may control several different things

I was watching this:

and was thinking that there may be a way to accomplish the same results with the Tahoe..

you can always try, not sure if something like that would work though, gm uses a digital serial bus and self checks it's self some things check once per key start and other things thousands of times per key start. so if you were to ground some wires together like this guy did it will know and probably send a error message. when I use my tech2 to scan my truck it knows the things I did like I cut my bose mic's so it gives me a error, I attached my puddle lights to my interior lights gives me a error for that as well, neither one of those are messages that would come up in the dic but if they were it probably would show them.

I am certain you are probably aware since you seem to have done a lot of research on this subject but the TPMS sensors signal is picked up by the RCDLR module.

That is the Remote Control Door Lock Receiver module... which is the same module that picks up your remote controls for your door locks and remote start and such. It is located in the drivers rear quarter panel by the power lift gate motor if your truck has that option.

Perhaps you could do something with that since it is what sends the signal to the BCM... I don't know, just a thought.
