ONNECTIONS
:
1. White Wire (1)
Connect to either the wire activating the air-conditioner compressor clutch (with a 3-way splice) or directly to the air-conditioning
activation sensor.
2. Orange Wire (1) OR Yellow Wire (1)
One of these wires is connected to ground, depending on whether the air-conditioning power source is normally open or normally
closed:
In a normally open air-conditioning circuit, the air-conditioner sensor wire (white wire) has no current flow when the air-
conditioner is off. When the air-conditioner is activated, current flows in this wire. In a normally open system, attach the yellow
wire to ground.
In a normally closed circuit, the air-conditioner sensor wire (white wire) has current flow when the air-conditioner is off. When
the air-conditioner is activated, current flow will cease to flow in this wire. In a normally closed system, attach the orange wire to
ground.
After connecting the appropriate wire to ground, the remaining wire should be cut off and capped with a wire end cap. No connec-
tion is made with this wire.

NSTALLATION
:
Two electrical control modules are required for dual M350 installation. The 12 volt DC power source must be capable
of providing 100 amps of current. Two temperature sensors are used. Generally only one unit must be activated by the
air-conditioning system.
FINAL NOTE: After wiring the electrical control module, either:
A. Cut all unused wires as close to the module as possible; or
B. Bundle unused wires with the tie straps provided and secure to vehicle. Wire end caps provided in the kit should be
installed on all unused wires to prevent possible short circuits.
