Muncie 4-speed and back up light switch
Does anyone have a diagram of the wiring for the backup lights and typical switch used on a Munsie 4-speed circa 66 to 68 A-body. I don't find the wiring diagrams in the CSM very clear for a novice. What are the inner workings of the switch. Is it strictly on/off. There are no instructions on installing the switch and adjusting. Anybody care to comment and give some instruction.
Attached is a somewhat typical application.
Thanks
Wayne

Yes, it is just an on/off switch (what else would it be?). It makes contact when the shift linkage is in reverse. The dash harness has two green wires that to to the NSS on the steering column. Just extend those down to the switch on the trans. No, since it is just an on/off switch, it does not matter which wire is which.

Thanks all. So here is what I have to do on this project.
I needed the harness for the B/U lights that goes from the bumper and is attached to to pinch weld and fed thru the body into the trunk and is inserted into the rear harness. I have that and have seen the instructions to drop the bumper for install and at the same time insert new rear bumper fillers.
I found Chevy instructions on setting up the switch on a Muncie so I have read that and also noted the gage pin for setting nuetral. I will purchase the proper switch.
There is an egsisting harness coming from the dash area that has the water proof ending that has two green wires that Mike mentioned. Should I test it somehow?
I know the purple wires but I see no jumper.
Anybody have the jumper or know where I can get one.
This was good information. Much appreciated. I need a lead on the jumper insert.
Thanks

PS: This car is a 4-speed car but I believe the the steering column was a replacement maybe a later year which has a switch on it that is not connected to anything?
