Hey guys, hoping some of you may be able to help out before the winter really sets in.

I'm trying to install a ProStart CT-5000 into a 2003 Cavalier and I already have the Titan G.M. Passlock I & II Bypass Module with second ignition.

My biggest problem is trying to match up the wiring from the different instructions.

If I list the wires I'm looking for, can anyone help out?

Thanks and happy holidays!

Christopher

(btw, I noticed there's no wiring schemes on this site for the 2003 (?))
