Bare with me dad's the mechanic I'm the tech.

I have a short in the wires coming from the A/C controls in the engine bay just past the firewall that melted the wires and vacuum lines. But you can't really get to them because of the heater core pipe.

So he said he was gonna drill a new hole higher up to put them through where they arent as conjested. He said its either that or pull the engine... and we just finished a swap so thats not an option.

But we can't trace all the wires... Got one vacuum line, controls to TBI I believe... and from out side we lost one small black wire and one big black wire... All the other I believe are accounted for at the controls...

Thanks in advance for all your help.
