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.
The Throttle Position sensor attaches to the main harness .
