INSTALLATION
1. Inspect the Main System Harness, making sure that all connectors and
grounds are properly in place.
2. Because the harness extends from the engine compartment into the
passenger compartment, a hole must be drilled in the firewall on the
passenger side. Cut two overlapping 1 1/4-inch holes on a 1-inch center in
the firewall. Saw the pointed edges to create an oval-shaped hole.
NOTE: An alternative to this method is to cut a single 1 3/4 inch hole.
3. Extend the fuel pump relay, ECU connector, and Calibration Module relay
through the firewall hole into the passenger compartment.
NOTE: The T-connectors at the joints of the Main System Harness are closed
by snap fasteners which can be opened by hand or with a flathead
screwdriver. Once open, the T-connectors can be rotated for ease of
installation, if necessary.
4. The 3 1/2 x 2 1/4-inch aluminum plate included on the harness mounts over the firewall hole using four hex head sheet metal screws.
NOTE: Start the screw holes with a pointed punch or small drill.
5. The wire harness is assembled with the aluminum plate flush against a T-connector. The black plastic casing on the wire harness can be
cut to allow the plate to slide up the harness to the correct location. Once the harness is in place, the casing should be reattached on both
sides of the firewall.
CAUTION: When feeding the wire harness through the firewall, be careful to not damage the wires against the cut sheet metal.
6. A rubber grommet is provided to protect the wires in the aluminum plate. Use RTV to seal the plate to the firewall.
7. Install all connectors according to the list and diagrams. The harness has been designed so that each connector is unique and will fit only to
its correct match. There is only one possible installation combination; it cannot be installed incorrectly.
