Truck isn't powering trailer running lights, but brake and blinker lights work
I'm borrowing a friend's truck to pull my trailer this weekend, and when I plugged my pigtail into his truck the running lights didn't come on. The blinkers and brake lights work, as does the brake cotroller, so the connection is at least partially working.
I "shorted" the running lights by sticking a fuse in my pigtail and they all came on so I know they work. It seems that something is amiss with the truck. Any idea what it could be? All 7 pins at the connection look good. Is it possible that a wire broke somewhere in the truck harness? Could there be a fuse in the truck that ONLY affects those pins on the connection?
