    Guys,

    Got problems with trailer lights and need help. I know the trailer lights are fine and problem is my truck. Problem cropped up about a year ago but I dont know exactly when / why. Here is what I have trobuleshot / done so far.

    -No lights, turn signals, flashers, or brake lights
    -Electric brakes working
    -Replaced underhood Fuse 21
    -Replaced underhood Fuse 67
    -Replaced underhood Fuse 73
    -No lights, turn signals, flashers, or brake lights.
    -Used 4 Pin Tester. Got “Tail” green but “LT” and “RT” dead. Used 7 pin to 4 pin converter and got same results with Tester.
    -Swapped underhood Relay 9 and Relay 6 as I have / will never hooked TT to truck.
    -Same results with 4 Pin tester and no lights on trailer when tried.

    Thanks in advance for help.

    Josh
