2. Uncoil the wiring harness and route the end of the
harness with the short red and black wires - with ring
terminals installed- from under the vehicle up into the
engine compartment on the battery side.
3. Position the red and black wires (with terminals) near
the battery and prepare to route the five foot section, with
connector, into the vehicle operator compartment area.
NOTE: The relay for the ON/OFF control is located in the
engine area and only requires a 3/8" hole for routing the
smaller power lead terminal into the cab.
4. Look for an existing hole, with rubber grommet, in the
vehicle firewall. The hole must be 3/8" or larger.
DO NOT drill any holes until a thorough visual
inspection is performed to determine that the
area around the hole to be drilled, on both sides
of the firewall, is clear of any obstacles such as
brake lines, linkage or vehicle wiring.
5. If an existing hole is not available, look for an area to
drill the hole that satisfies these conditions;
• Hole should be drilled on the same side of the vehicle
firewall (left or right) as the vehicle battery.
• DO NOT put a hole in such a spot that will force the
wiring harness, when installed, to interfere or be routed
behind accelerator pedal, brake pedal, clutch pedal,
parking brake or associated linkage.
