key doesn't engage starter, schematic needed
My 93 coupe won't engage the starter with the key switch. It used to only happen once and a while, now it never works. I ran a wire down and tied into the small wire on the starter, connect that to 12V to engage the starter now. I wanted to get the key to work. I bypassed the VATS with a 7.25K ohm resister, and it still won't start. I located the starter relay under the dash. There are some other wires tied into this relay that I don't think are supposed to be there. I suspect a loving gift from the previous owner. I want to remove whats not supposed to be there. Does anyone have a schmatic, or wiring diagram that shows this relay? I do have a service manual, but it's a preliminary manual for the 1993. It scares me to be in where the SIR system could activate. I'm thinking that if all else fails, I could run 12V from the key start wire directly to the starter. I realize it could start in drive then. I sure wish I knew what the wires did and where they go. Thanks!

That is very unlikely to happen. The SIR system discharges when the key is off and can't fire after a few minutes. The normal way to disable it is to pull the fuse and wait 5 minutes (way more time than you really need).
