If you use the 7-way that is used for commercial/industrial/agricultural application like # PK11720 or the RV/standard 7-way like # HM47210 you will need to utilize the same location. The reverse signal should be connected to the center location of either application.

You will simply need to make sure your wiring corresponds with the function locations. I've attached a photo to assist. For a 7-pin that normally does not have a reverse light, that means utilizing the auxiliary in the middle for that function.

The reverse light circuit of a vehicle will have 12 volts on it when the vehicle is put in reverse. You would want to be careful using this circuit to power just anything though as it does have an amp rating that if you exceeded would blow a fuse.…
