I've spent a few hours under my '69 refresh project, installing new tanks, fuel lines and an electric selector valve. And while I was looking at stuff underneath I found something I wasn't expecting—a single wire with a very factory-looking connector on the side of the 3 speed transmission.
After disconnecting the wire, I found the other end was connected to nothing, terminating in a crimp-on female spade. The connection on the transmission has a round rubber-like pad with a single threaded stud in the center. It is on the left side of the transmission, just forward of where the external shift arms go into the 'box.
Knowing almost nothing about this rig's history, I really can't say that this is definitely the original transmission from 1969. But ANY electrical connection on an early Bronco transmission seems odd to me. It's only a single wire, so it's not a backup light switch. Did later Broncos have a top gear switch like some cars to mess with the timing for emissions?
Or is there something else I haven't thought of?
