Hi, can anyone help me I need to know how to wire up reverse lights on a 4 speed. I just swapped it in its a barge-Warner t-18 4 speed and I kept my original column for an automatic. The transmission has a thingy sticking out the top that looks like you can wire into it it has a metal stud on it. Please any info would help thank you

Here you go, if you can not get that harness to work, just wire a toggle switch to some led cubes hanging off the back bumper.

I believe the 73 with an auto had the reverse light switch on the underside of the steering column like where the safety neutral switch is.

Look for the wiring to connect from the trans harness to that?

 

More reverse light intel. Thanks to mikeo0o0o0

"When the trucks came with a manual trans, there was a dummy plug used to bypass the NSS switch. I've never been able to come up with a part number for the dummy plug. To bypass the automatic set up: Unplug the switch and discard or ignore. There are four wires in the harness plug, two each, red w/ blue trace and black w/ red trace. Run a jumper between the red/blue and red/blue, do the same for the black/red. That completely bypasses the NSS switch. Your truck will now start and the back-up lights will be permanently on. Now on to the backup lights.

In the engine compartment is a little U shaped jumper wire. It'll be located on the drivers side splash pan, just in front of the firewall where the wiring harness comes through. Unplug the little jumper, this will shut off the back up lights. There should be a back up light switch on the trans cover. Run two wires from the switch to the two wires that were jumped. This will get your back up lights working again.

Just a note, you could make a jumper plug out of the NSS. Cut the switch off the harness and splice the two pairs of wires. I just hate to cut these switches up. New, they're getting pricey. Here's the little jumper in the engine compartment.
EDIT: If you don't care about the back up lights, just jumper the red w/ blue trace wires. This will by pass the NSS but the back up lights won't work."

 

Thank you, this info really helps. thanks again.

 

Was up in the shop working on my red truck...I just figured out what the coiled up wire is on the dvrs side inner fenderwell. Suppose to be connected to my NP-435 and it has a 2 90* plug like the one I the pic. Even has the bracket that bolts to the trans, the trans plug is black taped up.
