Ok the car was originally a 1987 L98 Iroc with Auto trans and A/C. I pulled the car engine out almost a year ago, and removed the ecu and correspondng harness at the same time. I have tracked down most of my wires...I know stupid me, but I got a little carried away and didn't label everything...I have traced the wiring diagrams and found most of them like I said except these in the following pics...any help figuring out what these are would be greatly appreciated, thanks!


These wires come from the harness the penerates the firewall by the brake booster closest to the fender




This Harness penerates the fire wall low on the pass side next to the tranny tunnel..oh I lied in the picture...the wire is not green it is lt. blue
