CONNECT ONE FROM EACH SIDE OF THE POWER CENTER TO THE 100 AMP FUSE AS
SHOWN IN THE WIRING DIAGRAM.
Plug the Switch Panel Cable into the 12 pin connector located at the top of the Power Center.
Connect the other multi-conductor cable to the 8 pin connector. Refer to the wiring diagram supplied with
this kit as well as the wiring information supplied with all your various accessories and route all wires,
including grounds, before making any final connections. Use rubber grommets whenever wires pass through
metal openings and don’t allow wires to touch sharp corners. Additional detailed diagrams can be
downloaded and printed from our website.
Dress your harness by starting in the middle and working your way toward the ends of cable bundles,
keeping wires parallel for a neat appearance. Dress the wires to each accessory working from the cable
bundle, making sure to leave some slack (service loop) when you make the final terminations.

TESTING
Once you have completed installation of your wire kit, make sure the ignition switch and all
accessories are turned OFF and the battery is disconnected. Using a higher amp rated fuse than indicated can
cause serious, irreparable damage. IF YOU BLOW A FUSE ALWAYS REPLACE THE FUSE WITH THE
SAME AMP RATING.
a. Turn on the Master Disconnect Switch and use an ohm meter to check for shorts between the positive and
negative battery cable terminals. Resistance should be greater than 100 ohms. A reading of less than 100
ohms indicates a possible serious short or wiring error that must be investigated and corrected before
proceeding. Otherwise, connect your battery to begin testing the system.
b. Verify the brake lights illuminate when the brake pedal is depressed. Verify the horn.
c. Turn on the Interior Lights switch (up). Verify the Switch Panel rear LED interior lights come on.
d. Turn on the Lights (switch down). Verify the LED interior lights turn off and headlights, dash lights, and
running lights illuminate.
e. Turn on the Water Pump (switch up) and verify it operates.
f. Turn on the Fan (switch down) and verify both the water pump and cooling fan operate.
g. CAUTION: With your foot on the brake, Ignition Off, and the vehicle in neutral or park or clutch
depressed, momentarily bump the Start switch and verify the starter engages. Disconnect the battery if the
starter continues when the Start switch is released. This is commonly caused by a defective starter or starter
solenoid, or an improperly rebuilt starter. You should also check the neutral safety function by putting the
transmission shifter in gear and verifying that the starter will not operate.
h. Turn on Accy power (switch up). Verify windshield wipers operate as well as any equipment (transbrake
shown on wiring diagram) connected to the Accy Pwr output stud. Fuel Pump(s) should not turn on.
i. Turn on Ignition (switch down). Wiper and Accy Pwr should remain on. Verify the blue ignition indicator
on the Power Center illuminates.
j. Fuel Pump 1 should turn on with the Fuel 1 switch (up) and both fuel pumps should operate with the Fuel2
switch (down).
k. Verify left and right turn signals operate.
l. Verify the function of NOS1 and NOS2 switches. In the down position each switch should ground the Arm
terminal on the rear of the panel. In the up position both Arm and Purge terminals should be grounded,
controlling nitrous system Arm and Purge solenoids.
