compartment. Secure the wires as necessary using cable ties.
☐
Unplug the SEIC pigtail from the SEIC interface plug.
☐
Splice the red wire running from the VMAC 4 pin interface connector to the

white wire with violet stripe (CMC25).
☐
Splice the blue wire from the throttle control to the grey wire with brown stripe
(CET22).
Route the following wires into the engine compartment via a grommet in the
firewall*:
☐
*Grey wire with the green 4 pin connector (temperature sensor).
☐
*Grey wire with the black 3 pin connector (pressure sensor).
☐
*Orange wires, with black 3-pin connector (PTO heater cable).
☐
*Red and green 14 AWG wires (PTO inverter power wires).
☐
Cover all of the engine compartment wires with plastic loom.
Routing and Connecting the PTO and Compressor Wires
Route the following wires down the firewall, and behind the inner fender to the
compressor*:
☐
*Orange heater wires: Connect to the heater in the compressor body.
☐
*Grey cable with green connector: Connect to the temperature sensor in the
compressor.
☐
Route the red and green inverter power and ground wires to the driver side
battery.
☐
Connect the green wire to the nut on the negative terminal clamp.
☐
Connect the red wire with the fuse holder to the nut on the positive battery
terminal clamp. Ensure the fuse holder is protected and readily accessible for
servicing.
PTO Harness connections*:
☐
*Connect the PTO pressure switch and solenoid plugs to the solenoid and
pressure switch at the top of the PTO.
☐
*Route the PTO pressure switch and solenoid harness into the cab along the
same path used for the compressor heater and temperature sensor.
☐
*Connect the red wire with the blue bullet connector to the white wire on
the 4 pin interface cable.
☐
*Connect the black wire with the ring connector to the good ground
☐
*Connect the black wire with red bullet connector to the black “PTO
