bcm / plug help
first off i dont know what the bcm looks like. I took my harness out of my car and i dont know whats what. I have a wire diagram but its pretty vague. Im converting my harness to a "race car" harness so im ditching pretty much everything. Do i still need to run a bcm? Or can i get away with just my pcm running my engine? All i need to keep is my headlights, tail lights, brake lights and my power windows, everything else is gone. If i do need to keep it, is this what it looks like? And does anyone know what these other plugs are? the blue plug has one wire going to one of the relays, one going to the obd plug under the dash, one goes to the intrument cluster as a tach. signal and one goes to one of my brake switches. But i cant find anything it would have pluged into to.
Its a '94 car...

I can tell you one thing...you don't even have a BCM, because they only came in 1996 and later f-body cars.
I think the module in the top pic might be the VATS module.

i might be misunderstanding what you're asking, but the white, blue and black connectors pictures hook up under the passenger side of the dash to your PCM harness that goes through the firewall. you can see what all this wiring is somewhere on Rob's website.
here's some stuff on those:
http://shbox.com/1/harness6.jpg you can see what the connectors are called here
http://shbox.com/1/harness.htm here's a reference of the whole engine/PCM harness showing those connectors again
http://shbox.com/1/harness_connector_faces.htm on this page there are tabs on the bottom left of the page that shows what each of those connectors has in them for wiring for the various years.
Oh and yeah, that module in the second pic you have is passkey/vats.

The other little plug, the black wire goes to the relay then the other one goes under the hood.
