1800E OD wiring

posted by  someone claiming to be Bill on  Sat Mar 6 12:03 CST 2021 [RELATED]

I replaced my clutch in a '72 1800E and the wiring is "not stock" to the OD switch or the back up switch. I can't remember what goes to what since I took it apart quite some time ago.
There is a 2 terminal switch that looks like a Turtle candy on top , reverse switch??
Then there's a 3 prong horizontal placed switch I believe for the OD and one of those wires goes to the OD solenoid.
I am not good at following electrical schematics so.....

    The switch on top is the overdrive lockout switch. 1 wire goes to the solenoid on the overdrive, the other wire goes to the overdrive switch on the steering column.

    The other switch on the side of the shift cover is the reverse light and seat belt reminder light. 1 wire has fused power coming from the fuse box, 1 wire goes to the reverse lights and the other wire goes to the seat belt warning light on the dash.

    The reverse/seat belt switch has 3 male blade terminals and originally there was a paper label with colored dots representing the corresponding wire color next to each terminal , but that is probably long gone.

    I've got those switches in stock and I'll see if the switches also have numbers cast into the switch that identify the terminals.

    You can just try swapping the wires around until both reverse and seat belt lights work correctly.

      Eric, Thanks for responding so quickly to my question. You don't need to go through the bother of looking for what the 3 terminal switch terminals represent.
      I'll figure it out from there. In fact, I really don't care about the safety belt
      light since Bill Simpson's belts hold us in place.
