I belive it's an ESC module, but nobody (GM, Oreilley, etc) knows why the part they pull off the shelf does not look like the one I need....
This is the culprit...now if I can just get it ordered! Thanks!

 

Nobody at parts store knows how to look it up. The one they pull off the shelf as "ESC" module looks different than mine and looks just like my buddy's Camaro ESC that is mounted on the relay bracket. Mine has it's own bracket on the firewall and is on the opposite side of the brake booster. Some cars dont have the one on the firewall like mine...can anyone explain?

 

This is the one they always pull off the shelf. This is the wrong one. Mine has two (rounded corner rectangular weatherpack) plugs protruding normal to the face, not one plug on the edge. We're thinking it may be a Firebird only part, but not sure.

 

the box near the brake booster is the headlight door module. the last pic might be for the ESC. not exactly sure.

 

You are sure that it controls headlights??? My motor runs differently when I swap it out with a friend's module. I tried to circle the same part twice. It's to the left of the booster.

 

Well looks like you're probably right! Here is an earlier explanation and a better pic of my part.

This still doesnt explain why it runs differently when borrowing a friend's module. Can anyone enlighten me?

 

Maybe yours is faulty and pulling a lot of juice?
