1.
As a precaution, disconnect the
ground of the battery (if there is
more than one battery, disconnect
both grounds).
2.
Locate the rubber grommet
located on the driver’s side firewall.
Using a utility knife, make a 1-inch-
long slit in the grommet at the 11
o’clock position. See
Figure 1 for
proper location of required cut.
3.
Remove the lower dash panel
from the vehicle by removing the
two (2) screws at the bottom corners
of the panel (retain for reinstallation).
NOTE: There are also two (2) clips
located at the top corners of the panel,
which hold the panel in place. These
clips can be released by gently pulling
on the corners of the panel. Use
caution to avoid damaging the panel
during removal.
NOTE: On vehicles with a center
console it may be necessary to
remove the console to ease removal
of the lower dash panel.
4.
Locate the large grommet under the
dash where the main (large) wire
harness penetrates the firewall. Pull
the grommet away from the firewall
to allow the Banks wire harness to run
through the 1-inch slit, cut in
Step 2.
5.
Locate the end of the Banks brake
wire harness that has a GRAY and a
PURPLE wire pair (with inline
connector). Push the end of the
harness through the hole in the
firewall starting from the interior of
the vehicle. NOTE: Taping the end of
the harness to a piece of stiff wire (i.e.
coat hanger) may make routing the
harness through the firewall a
simpler task. The stiff wire should be
pushed through the slit in the grommet
and then the wires can be attached to
the stiff wire and pulled through the
hole in the firewall.
CAUTION: Pull gently to avoid
damage to the wire harness
connectors. Always pull on the
wire harness convolute sheath
rather than the wires themselves.
Continue to pull the harness through
the firewall until the branch
containing a GREEN and a BLACK
wire comes through the firewall.
6.
Route the PURPLE and GRAY wire
pair to the coolant temperature
sensor as shown in
Figure 2. The
coolant temperature sensor is
located on the front of the engine
near the center on the top side.
