Very Useful Electrical Wiring Diagram for your Hitch Connector

This is one of the best electrical diagrams I've seen. I'll be using this in the future. Its all the way down to 45 degrees F in Texas right now (brrrrr) so I'll wait to do too much outside stuff.

We'll use this for our travel trailer as we need to figure out a problem with our trailer brakes.
