View Full Version : Trailer lights...

Used a tester to test all connections and found out:

Left flasher/break is not working on truck-side harness.

How do I go about fixing this? Follow the wire up to where ever it connects for power and check it there?

Follow it and look for breaks in the wire.. The wires should go to your rear truck lights.

Also alot of newer trucks come with Trailer plugs built in.
