4) Right side high intensity only (brake & turn)

If your truck lead for the passenger's side high isn't good, your trailer will have everything but the right side brake and right turn. It would be good to make sure the truck wire was good before you started in on the trailer. It might save some head scratching. Turn your right turn indicator on and use a test light to see if you can find a blinking hot wire at the plug.

If you don't have a multimeter, you can use a tester like this:

You could also pick up one of these easy truck testers:

Some adapters have lights as well:

Thank you so much! I just went outside and backed the truck up to our utility trailer and it did the same thing as it would when it's connected to the MasterCraft trailer. So now that we've determined it is the truck, what needs to be replaced? Just the plug or the whole wiring? It's a 2000 Chevy Suburban.
