Maybe this will help? I have the 79 parts Bronco that has the plug and wiring still connected. If the above stuff does not help any.

Thanks brother if anyone has a 77 switch that would be great. Ford only made the switch for one year so I may retrofit a 78 switch in

Figured it out thanks to 77&79F250, you are the man!!! Had to wire up a 78 ignition switch since 77 switches are hard to find. Soldered it in and working great. Thanks again
