The Power Harness
• Both the monitor and camera require their own individual 

power sources. Connect the (RED) +12VDC wire to 

ignition/switched on power and the ground (BLACK) wire 

to chassis ground. If interference occurs or camera has 

difficulty connecting to the monitor, try tying the ground 

wire into an existing ground wire or run a ground directly 

to battery. 

• These are the only wires needed to power the entire 

system and all the cameras. Each camera can be seen at 

any time by simply pressing the power button and using 

the V1/2 button to toggle. Any additional camera can be 

accessed by toggling the MODE button.

• The four positive trigger wires (CH1, CH2, CH3, CH4) each 

represent one channel and will turn on their channel when 

the trigger wire is energized with +12VDC.

• Camera 2 is the designated backup channel. To have the 

the backup camera come on when you go into reverse, 

connect the CH2 wire to reverse power (or any power 

source that comes on only in reverse).

• The other channels can similarly be triggered (i.e. side 

cameras can be triggered by the turn signals etc.)

• To automatically have the monitor monitor turn ON when 

the vehicle turns on, tie the power wire into any key on 

ignition source. 

• To have a specific camera come on with the monitor, tie 

the camera trigger wire into the keyed ON ignition source.

Note: When the channel wire is active it will have precedence over the 

other triggers. Therefore, if you wish to use multiple triggers, do not 

attach the trigger to constant power.
