Master Lock Towing Camera Installation and Operation Instructions:
Camera Features
Camera Installation:
The camera has two mounting options/applications:
1) Back-up Camera- Slide the camera assembly inside a 1-¼” or 2” hitch receiver tube. The
magnet in the camera base will hold it securely in place. The plastic guide on the camera
bracket will help line the assembly up with the hitch pin opening and allow a standard or
locking hitch pin to be used for additional security.
2) Hitch Alignment/Load Monitoring System- Mount the camera to any
metal surface on the back of the vehicle using the magnetic base. The soft
pads on the base will prevent sliding or scratching and the camera bracket
can pivot up to 90° to allow the field of view to be adjusted.
Camera Power Connection:
The camera is powered by plugging the camera power
connector into the vehicle’s towing wiring harness. The
camera power connector is a 4 position connector that
directly attaches to many vehicles. The camera power
connector also has a pass-though design feature. This
allows you to plug your trailer wiring into the open end
of the backup camera power connector and monitor your
trailer load while towing. Some vehicles may need a 7
position to 4 position adapter, which is not included.
Note: A readily available 4 position tow wire extension (not included) will allow the camera
to be mounted further away from the vehicle plug for gooseneck or fifth wheel trailer hitch
alignment applications.
Notice: Depending on the make/model of the vehicle, the running lights or headlights may
need to be turned on to power the vehicle’s tow plug.
