1997 Ford F150 V8 Four Wheel Drive Automatic 139000 miles
My problem is when I hook up a trailer to my truck via the 7 way factory plug the lights on the trailer come on rite away even with no running lights or turn signal lights on. When I press on the break the lights on the truck go on and the lights on the trailer go out. The same is with the hazard and turn signal lights.
The running lights work as well. I followed the wires up through the truck up to the fuse panels under the hood and cant figure this out. All I want is for my trailer lights to be in cordnation with the truck.
