1989 f150xlt lariat with 5.8. C6 4x4. This harnes comes through the floor on the drivers side just under the main loom and to the right of the computer. I cannot remember where it was spliced in. I think it's for trailer brakes but after installing the stroker I can't remember where this was spliced in. All help and suggestion appreciated. Gage's on dash do not work but I think that is because I have sending units on this block instead of gauge units.
Wires are cut on the end. One larger gauge carrying power two others show no voltage Same harness possibly clear picture I am posting from my cell phone
Are the wire colors red, blue and orange by any chance?
If they are then it's the factory trailer brake wiring, one will be power (red) to brake controller, blue will be brake output from brake controller to rear end and the orange is brake (that's what ford calls it) but I've never seen it hooked up.

Yes those are the colors,,, my truck has alot of strange factory options i do not see on other trucks of this year.. but you nailed it and i am sure that's what these wires are.... they had quick clip splicers on the ends of the wires , this truck also has a remote start box on it and another strange looking box up under the dash that i am sure is used to log data of some nature
i traced back into the engine bay and there it goes into a loom.. my bundling pipe is very old and cracks easy so i hate to tear it all open .,, unnecessarily
