I went all over town todday to find a plug for my back-up lights that go into the tranny. I finally went to a-1 brakes and the guy told me to go into the yard and have a look around.
After about 1.5hrs i came out with 4,
Anyway , I tried one of them and it fit in nice and good so I think it should work, There is 2 wires, I figure one goes to the rear of the truck and splits into 2 for each light and the other one needs to go to a power supply.
Where abouts do I hook it up If my thinking is correct?

I am not very knowledgeable about the wiring on these beast, its not my fancy, but it has to be done,
once again i appreciate any tips,help,hints,ideas.

Wish i had a shop to work in, id be at er all night. Then id eventually figure it out and wouldnt have to bug you guys with my stuid questions.
It just gives me a better idea when I go at er tomorow

 

First tell us what truck you are working on

Most wires from the transmission go to the firewall to a connector ,to be routed through the main light harness down the driver's side frame.

 

One of the clues would be the color wire going to the switch you have. Most of the time Ford kept the same wiring code, so see if you can find that color wire where Dennis said to look.
