Installation of Harness
You may need to lengthen or shorten the oxygen and IAT sensor wires. It is recommended that this be done by soldering and
sealing your soldered connection with heat shrink. Standard butt connectors are not recommended.
1. Lay the wiring harness along the left-hand side of the intake manifold with the idle air control valve, throttle position sensor, and
engine coolant temperature sensor connectors at the front of the engine.
2. Connect the sensors mentioned above to their mating components.
3. Attach the eight fuel injector connectors.
4. Plug the MAP sensor connector into the MAP sensor, located on the left hand side of the intake manifold plenum.
5. Install the ECM connectors. Your ECM connectors on the harness can be identified by the clear or smoke colored alignment keys
- J1 - smoke, J2-clear. The outside of each connector on the ECM is labeled J1 or J2.
6. Install the coil wire assembly, part number 12097982. One end attaches to the top of the coil, the other end to the rear of the
distributor.
7.
Attach the connectors from the harness to the distributor and the ignition coil.
8. Plug in the fuel pump and ignition relays.
9. Attach the knock sensor connector to the knock sensor. Use care in routing the wiring harness to the connector so that the
harness will not be damaged by heat from the exhaust system.
10. Attach the B+ lead to the big terminal at the starter. A fusible link should be added at this connection for added protection.
11. Connect the fuel pump leads. The installer must provide a wiring harness from the fuel pump to the leads provided.
12. Connect the ignition lead to the ignition switch and attach the tachometer lead if there is one in the vehicle.
13. On your harness you will notice several different grounds. The grounds must be grounded on separate studs on the engine.
Failure to use separate ground studs may result in improper engine performance or ECM failure.
14. You will also notice two tachometer outputs from the harness, tach1 is for a standard negative side of the coil driven tach. Tach2 is
for new digital tachometers; this is a 0-12 V square wave output. Select and connect the proper output for your application.
15. Reconnect your battery cable.
Upper Intake Manifold Installation:
1. Attach the vacuum hose, part number 10216948, to the connector in the bottom of the plenum. Note: Another fitting will need to
be installed in the bottom of the upper intake rear most boss to supply vacuum to the brake booster and any other components
needing a vacuum signal. A 3/8 NPT fitting, part number 336018 or equivalent, is recommended for this application. Attach one
end of the vacuum line to this second fitting before the upper intake manifold assembly is attached to the engine.
2. Install the four intake runner gaskets, part number 12489372, on the lower intake manifold.
3. Place the upper intake manifold on the lower and attach using seven of the eight upper intake manifold bolts, part number
12490255. Do not install a bolt in the left, rear bolt location. (Note: This bolt will be installed with the rear accelerator/TV cable
bracket.) Use care when placing the upper intake manifold onto the lower intake manifold to ensure that the gaskets do not shift
out of place.
4. Torque the intake manifold bolts to 14 Nm (10 ft.lbs.).
5. Attach the ends of the vacuum hoses to the fuel pressure regulator and the power brake booster.
6. Connect the MAP sensor wiring harness connector to the MAP sensor.
7. Connect the intake air temperature sensor to the wiring harness.
