Monitor Wiring –
Crimp a fused lead from a switched positive power source to the red lead (pin C) of the power
harness supplied. Use a 10A fuse for the 8294-06 & 8294-06 EXT, and a 15A fuse for the
8394-07. Crimp a lead from the vehicle ground to the black lead (pin A) of the monitor power
harness. Shrink and seal the connectors with a heat gun after crimping.
The white lead (pin B) is for an optional “Stow Indicator” which could be attached to a relay or
LED supplied by the OEM. The circuit switches in a ground when the monitor is in a non-stowed
position.
All control functions are sent to the monitor via an encoded RF signal from the RF controller,
and no control wiring is needed.
The 8294-06 EXT has a proximity sensor. The red wire (pin C) supplies power, the black lead
(pin A) is the ground, and the white lead (pin B) is the signal for the proximity sensor to show
master stream versus an egress position.
Panel Mount RF Controllers –
Using the Panel Mount RF Controller template in the Component Mounting Templates section,
mark the panel cutout and mounting screw locations.
Cut a rectangular clearance opening and drill four (4) 7/32” holes.
Insert fixed RF controller case through the panel cutout. Secure the unit to the panel with four (4)
#10-32 screws. The length of the screws should be the panel thickness plus 3/16”. The screws
supplied are ¼” in length. Apply Loctite 242 or equivalent to screw threads before tightening
them.
The controller antenna is to be mounted using the 10’ antenna cable provided. Locate one of
the antennas outside the vehicle compartment, and in a position that provides the least
obstructed line of sight to the monitor’s antenna.
Place a 1A fuse between the red lead of the RF controller and a switched positive power lead on
the vehicle. Attach the black lead from the monitor base to the vehicle ground.
All control functions are sent to the monitor via an encoded RF signal from the RF Controller.
OEM RF Transmitter –
Place a 1A fuse between the red lead of the transmitter and a switched positive power lead on
the vehicle. Attach the black lead from the monitor base to the vehicle ground.
Connect all of the switch commons to the ground (black) connection.
Connect each function to a corresponding switch (see Table 2 on page 11). To operate the
function, close function’s switch to ground. Any combination of pushbuttons or toggle switches
can be used.
Power indication can be created by attaching an LED and proper resistance between the VCC
(+3V) and ground connections. Max rating for the VCC connection is 250mA.
The transmitter’s antenna is to be mounted using the 10’ antenna cable provided. Locate one of
the antennas outside the vehicle compartment, and in a position that provides the least
obstructed line of sight to the monitor’s antenna.
