Trailer Light Pigtail Wiring Diagram. This page has wire diagrams for many electric options including wires for trailer lights, brakes, alt power and connectors. Let's face it, you've lent your trailer to a friend or family member and they simply didn't check to make sure the connector pigtail wasn't dragging, or they accidentally got.
The wife and kids stare daggers into your head as you curse your way through hours of agonizing wiring mishaps. Dash back lighting and trailer lights on all the time. So here I have an older trailer which needed some work So the casing will help protect the light pigtails too.
This is accomplished by tapping into the tow vehicle's electrical harness to transfer power to the trailer wiring system.
Connect the wires from the lights to the new wiring.
Before connecting each wire slide an appropriately sized piece of heat shrink over each wire. Your trailer wiring plug doesn't match the one on your vehicle. Has anyone seen any info on this?
