MAKE SURE THE BATTERY IS DISCONNECTED BEFORE PROCEEDING. The Power
Center, 100 amp fuse holders, steering column, battery, lights, HVAC, all switches and other electrical
equipment should be mounted before you begin installing the wiring. The Power Center must be mounted
in a dry location, usually under the dash. It is normal for relays to get a little warm during continuous use
so the Power Center should be mounted where air can circulate around the unit.
Connect the negative side of the battery to the engine block if possible as well as to the chassis
using battery cable (not supplied) and at least 3/8” bolts and tooth washers. If grounding the battery to the
engine block is not practical, connect both the battery and engine to the chassis with battery cable, bolts,
and tooth washers. Metal must be clean, free from rust and paint where the connection is made. If the
body of your vehicle is metal, it too must be grounded to the chassis using at least 8 awg wire and 1/4”
bolts and tooth washers. If you have a fiberglass body, mount one or more ground studs and terminal
blocks inside the cabin for convenient ground points. Use at least 8 awg wire to connect all your ground
points to clean steel chassis.
Two 100 amp MIDI fuse holders and fuses are included with this kit. They can be mounted under
the hood or to the chassis, but must be at least 6” away from exhaust. One of the 100 amp fuses protects
the wires connecting the battery and alternator, the other protects the Power Center. Two separate 10 awg
wires supply battery power to the Power Center. BE SURE TO CONNECT ONE FROM EACH SIDE
OF THE POWER CENTER TO THE 100 AMP FUSE AS SHOWN IN THE WIRING DIAGRAM.

WIRING THE CAR
Refer to the wiring diagram supplied with this kit as well as the wiring information supplied with
all your various electrical equipment and accessories. Supplemental detail wiring diagrams are also
available on our website to assist you in correctly installing the system.
Route all wires, including grounds, before making any final connections. Plug the multi-conductor
Power Center cables and light sensor cable into the receptacles located at the top of the Power Center
Control Board. Route the cable leads to all the various switches and equipment as indicated on the
diagram. Be sure to protect the ends of any wires that aren’t used by doubling the wire and installing a
piece of heat shrinkable tubing or electrical tape. Use rubber grommets whenever wires pass through metal
openings and don’t allow wires to touch sharp corners. Heater/Ventilator/Air Conditioner (HVAC)
systems can be complicated so pay special attention to the manufacturers instructions and note that the
Power Center includes relays for the HVAC unit and blower motor (high speed) as recommended by
leading manufacturers.
