lt1 may have the 7mm screw, ls1 doesnt i think.

As for LS1 at least...(all from memory)...
there is a 7mm screw in the middle of a large connector under the dash, left side of steering column. Once that's undone, it'll disconnect from 2 dash connectors. then the firewall pass-though block has a tab on top and bottom you push in and the block goes into the engine compartment. the headlight harness is part of the harness that has the wheel speed sensors etc.

I'll look at the Trans Am tomorrow to verify
