Wire Harness/Connector Plug
A 7-way wire harness/connector plug is wired into your trailer to connect electrical power
from the tow vehicle for travel. This supplies power to the RV brakes, taillights, clearance
lights, turn signals, brake lights, etc. Wiring to operate your brakes must be the same size in
both the tow vehicle and RV (the RV brake wiring is 12-gauge wire).
When attaching wires to your tow vehicle, tape all the connections for moisture protection.
