    take a test light and start pickin wires

    none will be hot until you press the brake, turn signal, etc. then they will have power

    im not sute how the fords are run...but the left and right turns signals are each separate (obv) but when the brakes are applied, both turns signals are powered on...make sense? so that equals brake lights.

    the 12v int he middle is just for access. such as an extra dome light or soemthin....whatever...

    weve all had our trailer light troubles...good luck

    Check the fuses in the power distribution box under the hood on the drivers side or the fuse box in the cab. Trailer marker and turns were on seperate fuses.
