Power wire Installation
a.
Under the hood on the driver-side, locate
the grommet for the main factory wiring
harness on the driver side of the firewall
directly above factory wiring.
(Fig. 6-1)
b.
Identify unused nipple and slice the tip off to
create an opening for the power wire.
(Fig. 6-2)
c.
Under the dash area on driver-side, lubricate
power wire with silicone spray or
comparable substitute. Run through the
grommet. The wire will only go so far due to
the positioning of the factory wiring under
the hood.
(Fig. 6-3)
d. Once enough slack is visible, pull the
full
length
of the power wire through under the
hood. You want just enough length to reach
your battery. Cut any additional slack. Note:
Avoid interference with accelerator and
brake pedals
(Fig. 6-4)
e.
Secure any wire slack to existing factory
wiring. Use cable ties as necessary.
