Installing 4-Way to 7-Way Adapter 12V and Reverse Light Wires on 2017 Ford F-150

Question:

I am installing a bargman plug on my f150. I have the four way plug into the bargain plug just having difficulty finding which wires to hook up for reverse lights and charge wire. I spliced in the blue wire for the brake controller. Just not sure which wires on the factory truck harnesscolors to cut and splice for back-up lights and 12v auxillary/charge wire.

When using an adapter like the Adapter 4-Pole to 7-Pole and 4-Pole # 37185 on your 2017 Ford F-150 the reverse light wire will be a green and brown wire that you will splice into based on my research. The power wire will be an orange or red wire that will be run to the end of the driver's side frame rail. You will use that for the 12V auxiliary/charge.

I've attached a photo with the designated locations to assist.
