INSTALLATION OF WIRING HARNESS, CONNECTIONS AND SIx-GUN
DIESEL TUNER
1.
Disconnect the battery ground
cables from each of the batteries.
Secure the cables so that they do not
come in contact with the battery posts
during the installation.
2.
From the engine compartment,
locate the rubber grommet high on
the driver’s side of the vehicle firewall.
The grommet is about 3” in diameter.
Make a 1” x 1” cross-shaped incision
in the grommet (see Figure 2).
3.
From the engine compartment,
feed the grey three-connector cable
through the incision made in the
firewall grommet and into the cab.
From inside the cab, remove the
lower dash panel under the steering
column to allow access to these three
connectors.
4.
Locate the two black wire harness
locking connectors between the
brake fluid reservoir and the air
conditioning compressor. Lift the gray
connector locks and disconnect the
38-pin connector pair and the 24-pin
connector pair (see Figure 3).
