LOCATING THE AUXILIARY
SWITCH WIRING
There are three sets of blunt-cut and
sealed circuits. Two sets are under the
hood and behind the battery tray, and one
set is inside your vehicle at the passenger
footwell.
The powered set (A) is taped behind the
battery tray and has a red spot tape mark.
The second set (B) is also under the hood.
It is taped behind the battery tray and has
a white spot tape mark. This set routes to
the interior passenger footwell.
Remove the battery and battery tray to
access the underhood circuits. The interior set is taped on a wire harness
by the passenger side footwell. This set is
the other end of the circuits taped behind
the battery tray, with a white spot tape
mark.
Remove the fuse panel access door in the
kick panel to access the wires. If you do not
see them, you may need to pull them
down.
