INTRODUCTION
General Service and Safety Precautions
WARNING
Never service, repair, or troubleshoot this system unless you are a professional air
conditioning/refrigeration service person. Improper servicing can lead to serious injury or death from fire,
electric shock, or explosion.
Refrigeration and air conditioning devices are extremely complicated by nature. Servicing, repairing, and
Trouble-shooting these products should be done only by those with the necessary knowledge, training,
and equipment.
Installation General References
• Disconnect the negative battery cable before performing any work on the vehicle’s electrical
system.
• Bare sheet metal, for example around drilled holes, must be treated with anti-corrosive coating.
• Secure hoses, cables and wiring harnesses with cable ties and fit protective hoses around them at
chafing points.
• Fit edge protectors (split fuel hose, grommet, split-loom, etc.) to sharp edges.
• Replace hose clamps as necessary. Hose clamps should be inspected before re-use. Look for
damage to the screw and to the band due to fatigue, corrosion, or improper installation.
SPECIAL NOTES
Warning: All power connections are to be made at the battery.
Caution: Remove the three 15A fuses from the relay board and replace them with 20A fuses when an
underbody-mounted, or Valencia rooftop-mounted condenser is being used. Refer to page 8 for more info.
Be sure the thermostat connectors
are connected to the brass terminals,
not the silver terminals.
When making power connections, the battery connections must be made last. Failure to follow this direction
could result in a short circuit and damage to the vehicle or the system being installed.
Before cutting the mounting hole for the controller, be sure there is no structure or wiring behind it that can
be damaged.

In some cases, not all wiring connectors / wires will be used. In these cases, secure the unused connectors /
wires to the wiring harness and protect against damage.
Insert the blue wire labeled AC
BLOWER ON from
the NEO adapter harness into cavity C
of the blower harness X1 connector.
Connect the blower harness and NEO
adapter harness to the NEO controller.
Install the dome light bezel on the
package tray.
Connect the following connectors to
the
NEO controller adapter harness:
o coolant pump
o coolant valve
o compressor
Secure unused connectors to the wire
harness as necessary using electrical
tape.

Connect the extreme relay board
harness to the thermostat and NEO
adapter harnesses.
