Installing the Throttle Body
1. Place the supplied gasket on the manifold (see above) and place the
throttle body onto the gasket over the existing studs. The throttle body
linkage must be on the driver's side of the engine.
2. Install the original nuts and washers onto the four carburetor studs.
See Figure 4.
3. Tighten to 10 lb. ft. of torque in several steps using a crisscross
pattern.

Installing the Wide Band Oxygen (O
This is the key component of any EFI system. Only one sensor is
required. This sensor continuously monitors the exhaust gas mixture and
sends the information to the ECU where adjustments are constantly made
to maintain the air/fuel targets.
1. The supplied O2 Sensor Bung can be installed in either exhaust bank.
2. The Sensor connects to one of the cables in the main wiring harness.
See Figure 7 on next page.
3. The ideal location for the sensor is in the exhaust collector or within 8-
inches of the collector itself. It must always be at least 18-inches from the
exhaust tip, to prevent reversion and false lean conditions.
4. The sensor should be between 10° to 14° above horizontal (see figure
6 below) to allow condensation to run off. If this is not adhered to, the
sensor is susceptible to damage.
5. Never position the sensor on the outside of a bend in the exhaust
tubing.
6. The sensor must always be mounted ahead of any catalytic converter if
vehicle is so equipped.
7. Drill a 7/8" diameter hole in the desired location.
8. The supplied bung kit can either be welded in place or clamped onto the
pipe. The clamp-on style works well and will not leak. If welded, make
sure the bung is welded completely all the way around and does not leak.
Thread an M18-1.5 bolt into the bung to prevent distortion.
9. Install the sensor into the bung. Tighten securely.
10. Connect the O2 sensor to the sub-harness that connects to the
throttle body. See Figure 7.
11. Note: The O2 Sensor will not work on "Zoomie" style headers.
WARNING: Do not start the engine without the sensor cable con-
nected to the throttle body and the EFI system is fully operational
or damage will occur to the sensor!
