Where does this connect to?

[Born Lucky]

Attachment 639294I started installing a new wiring harness. I replaced the taillight and the harness that runs along the frame. The harness that runs along the frame has an extra connection. One ends in the rear by the taillight and the other ends by the firewall ( photo) Where does that connect to?
I am thinking that it is for the back-up lights, but I am confused where the connector reaches the firewall. One connects into the stop=taillght harness and I can not find the connection for the one I assume was for the back-up lights. See photo.

If your truck didn't originally come with backup lights, the hole in the firewall may not have been punched out. I believe it should be right below the stop/taillight plug

That is what I thought. I have the wiring diagram and it does not show where it connects to. Now if I punch a hole into the firewall where do I connect the wire.

It would depend on whether you have a four speed,





automatic/ 3 speed in the tree, theres a switch that would be installed in the rectangular slot in the steering column between the clutch and brake pedals.

Yes I have a four speed, just like the example you provided.
I would need the bracket and the switch and harness inside the cab.
Where can I find,buy the parts? Thanks

I would ask the guys on the forum if anyone has the pieces your looking for in a new thread. I have a used set for my project K10 as well as a NOS set in the for sale section.
