    Start with the easy stuff, clean the terminals, check the wires to make sure they're not cut or chaffed. You can clean the terminals with emory cloth or a small pipe cleaner and some electric grease to prevent further corrosion. If that doesn't work, then start tracing the wiring back and see if it's a wire splice or one of the connections. After that, it would depend on whether it was an aftermarket plug and play or stock 7-pin.

    It may be the lightbulbs also. I had this happen on a trailer & it turned out to need new bulbs. If that isn't the problem, then as Pugga said.

    Also check your ground wire on the trailer. It also could be the wiring harness box on your truck. These do go bad. I went through 3 of them on my 2005 Tacoma.

    With a new trailer. I would suspect your wiring harness on your truck. There is a box that the harness connects too. The box is the controller sorta speak. It could have gone bad, or your wire connector is corroded. Or the ground may need to be checked. If you don't have a volt meter, then you can pickup from the auto parts store a very cheap wire tester for a few bucks. It has a lightbulb on the end. This is a good way to test your wiring harness.

    Worse case scenario for $35 you can replace your wiring harness.

    I've had to replace this on my 2005 Tacoma several times.


    Here is the wiring kit for your truck(not promoting that you have to buy it from here, I was looking for a pic of a harness & found this one): http://www.suspensionconnection.com/cgi-bin/suscon/7275T.html

    They are super easy to install. About 10 minutes for installation.
