I hope someone might be able to help me out on here. We put a new trailer plug on our truck, used a tester on the plug and everything worked. hooked up trailer and nothing. put new trailer plug on and checked to see if any of the wires were bare. everything checked out good. hooked up trailer with diffrent truck and worked fine. I have power coming out for lights, brake, turn signals and 12 v aux for break away battery. I used this same truck and trailer for the last 2 years and everything worked like it should have, So whats my next step. All fuses are good also
