How to wire clearance lights with combination factory and single wire harness?

[xbrotherx]

The original owner of my truck installed clearance lights that have one wire coming from each light rather than the two (black and brown) that were standard.

I have a factory wiring harness that will plug into the socket at the passenger side kick panel, but my knowledge of electronics is not good enough to know if I can splice the two.

So my question is, with the setup that I have, can I cut the harness plug off the factory wiring harness and splice that to the single wire that would supply the clearance lights with power?

** wire coming from underneath headliner. you can see that single wire exiting the cab to the clearance light above.


** The comparison of the single wire versus the wiring harness's brown and black wires


** factory wiring harness plug and socket


** type of clearance lights installed

Those clearance lights must be grounded at each light.

The brown wire in your trucks harness should be the power wire, so just connect the brown to the wire coming out of your headliner.

Just tape off the black wire, it is the ground which you won't need.

Great! I'll give it a try and let y'all know what happens.
