2. Monitor Wiring
a) Place a 10A fuse between the red lead (Pin C)of the monitor and a switched positive
power lead on the vehicle. Attach the black lead (Pin A) from the monitor base to the
vehicle ground.
b) 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 and is limited to
250 mA of current when the monitor is in a non-stowed position.
c) All control functions are sent to the monitor via an encoded RF signal from the
transmitter; no control wiring is needed.
d) The 8500-01 EXT and 8593-01 EXT have a proximity sensor. The red wire (Pin C)
supplies power. The black lead (Pin A) is ground. The white lead (Pin B) is a signal for
the proximity sensor to show master stream versus an egress position.
3. 81327101 and 81327201 Panel Mount Transmitter
a) Mark the panel cutout and mounting screw pattern per dimensions in Figure 15
b) Cut a rectangular clearance opening and drill four
 0.219” (7/32” drill) holes.
c) Insert fixed transmitter case through panel cutout. Secure the unit to the panel with
four #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 to the threads of the screws
before tightening them.
d) The transmitters antenna is to be mounted using the 10 foot antenna cable provided to
locate one of the antennas outside the vehicle compartment in a position that provides the
least obstructed line of sight to the monitor’s antenna.
e) 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.
f) All control functions are sent to the monitor via an encoded RF signal from the
transmitter.
4. 81353101 And 81353201 Fixed Remote for Use with OEM Supplied Switches
a) 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.
b) Connect all of the switch commons to the Ground
(Black) connection.
c) Connect each function to a corresponding switch. To
operate the function close the function switch to ground.
Any combination of pushbuttons or toggle switches can be
used.
d) Power indication can be created by attaching an LED and
proper resistance between the VCC (+3 V) and Ground
connections. Max rating for the VCC connection is 250 mA.
e) The transmitters antenna is to be mounted using the 10
