    I have the OPT7 triple on my 2018. I had to get the backup camera module....I used the Curt T-harness and tapped into the wire in the middle wire of the 7 pin on the T-harness for the reverse lights.

    What was it doing before you got the module?

    It was recommended to have it. I just plugged it in line with the 4 pin plug. Didn't try it without it.

    You must have separate turn signal. I take it from the bcm under the dash driver side. And the reverse from the light.

    I did not use the 5 wire type, I used the four wire and just tapped off the center wire of the 7 pin plug.

    I you use the the 5 pin, just use a bullet style connector to hook the white wire to the reverse on the five pin plug part.

    The best is PUTCO BLADE tailgate light bar and they also have a y-connection harness that plugs from behind the bumper to the towing hitch light connection point. No splicing of wires and plug and play. The light bar is very bright and comes with 3 year warranty cant beat it.

    So, I could get this T-Harness https://www.curtmfg.com/part/56584 and just hook the 5th pin to the white wire and NOT have to tap into my truck's tail light wiring? That seems like a better way to install on of these light bars??

    That is correct. With the vehicle CANbus monitoring of the taillights, you really don't want to tap into the wiring for them. All of the outputs/wiring for the 7 pin trailer plug are fused relay outputs direct from the battery.
    To simplify the install, buy a 5 flat trailer pigtail. Then pre-wire the light bar and you just ha e to plug it in.
    Just an FYI: A four flat and five flat trailer plug are interchangeable for those that have light bars without reverse.
