Pretty self explainatory I can't seem to find the body control module, I am looking under the dash every where and must be blind or dumb because I cannot locate it. I have a few different boxes that look like they could be it but no clue which it is. Any help would be greatly appreciated.

Speed Sense yellow/black ac ECM, black 73 pin plug, pin 57

The ECM (Engine Control Module) is on the driver side fender, behind the headlight.

The BCM (Body Control Module) is to the left of the steering column.

Ok, this thing has like 500 miles on it and I don't want to jack anything up so I will post some pictures when I get home, but here is a general description of what I am look at:

 

BCM mounted to the floor board with small plugs and fuses on one side, with two large connectors on the back, does that sound right?

 

ECM mounted to the fender wall with a large plastic cover and a bunch of fuses on top?

 

Thanks for the help guys!
