If wireless the usually pock up power from the clearance lights in back so you need to turn on your lights in the truck when plugged in to the trailer for it to work
Thank you. After posting my question, thru trial and error, I figured it out.
1. Must have lights on
2. Truck must be running
3. The 7 pin plug must be plugged in
Thank you again for your reply
