Well, the other day my car (87 Bronco XLT 5.0) quit when I turned on the climate control. I have isolated the problem to the leads that power the ignition switch. Both leads show 6 volts, and jumping the other pins on the ignition switch get the accessories to start.

So, where do the ignition leads go through the firewall?

If the ignition leads go through that large connector behind the brake pedal, how does it come off?

Are the ignition leads fused in any way, and if so, where?

Thank you for the help. It is much appreciated.

Well this problem has finally been solved. The wire that runs from the battery to the firewall (12v lead for the ECU and the ignition switch) is spliced in the large bundle of wire that runs along the driver side fender wall. It tore it apart and found that the solder that Ford used had corroded, leaving me with a terrible connection. There was too much resistance across it for me to get 12v. I cut out the bad wire and put in a new length. Viola.
