How to Repair or Install Trailer Wiring

Securing your trailer wiring with a Scotch lock.

If you used a Scotch lock like I do to secure your trailer wiring splices, you're ready to lock it in place. Be sure both your factory and trailer wiring wires are still where you want them, then fold the top of the Scotch lock over and press it tightly together with pliers. This drives the metal connector into place inside so nothing can slip and everything makes a good connection.

Finally, fold the outer clip over on the Scotch lock and snap it into place.

Repeat these steps until you have installed the wires for all aspects of your trailer lighting. Remember to keep your work neat and tidy.
