Tow vehicle battery
The tow vehicle battery is the primary source of power for
your RV’s brake operation. To ensure available power when
needed, keep your tow vehicle battery and charging system
working properly.
Battery Isolator
(customer supplied)
You may want to install a battery isolator on your tow vehicle.
A battery isolator is a device that:
• Receives current from the tow vehicle alternator to
independently charge both the RV auxiliary battery
and the tow vehicle battery.
• Prevents the RV from draining your tow vehicle battery
(so you can start your tow vehicle engine).
Your dealer can assist you with the selection, purchase and
installation of this aftermarket part.
7-Way Wire Harness/Connector Plug
The 7-Way Wire Harness/Connector Plug is wired into your
FW to connect electrical power from the tow vehicle for travel.
This supplies power to the RV brakes, tail lights, clearance
lights, turn signals, brake lights, etc. Wiring to operate your
brakes must be the same size in both the tow vehicle and RV.
Maintenance
Corrosion may build up with extended use. CLEAN your
Connector Plug as needed to ensure good electrical contact.
INSPECT the 7-Way Wire Harness/Connector Plug periodically
for cracking and wear to make sure connections stay protected
from the elements as you travel. REPLACE if cracked or broken.
