300ZX Procedure

After splicing in the new injector sub-harness(es) (if necessary) and taping all connections, use the following revised routing procedures.

NOTE:
The injector sub-harnesses are wrapped in green tape for clarity. Actual injector sub-harnesses are wrapped in black and have two tape stripes for identification. The color of the identification stripes varies depending on the model and model year.





1. With the identification stripes toward the fuel pressure regulator, route the "passenger side" injector sub-harness UNDER the spark plug wires and PCV hose.





2. With the identification stripes toward the fuel pressure regulator, route the "driver's side" injector sub-harness UNDER the spark plug wires.





3. On the "passenger side", securely tie-wrap the injector sub-harness to the PCV hose in two places. Trim off excess plastic ties neatly.

4. After the intake plenum is installed, connect all hoses and make sure the "passenger side" injector sub-harness is routed UNDER the PCV hose and spark plug wires. Make sure the injector sub-harness does not come in contact with any sharp objects such as hose clamps and is not pinched in any area.





NOTE:
Do not route the "passenger side" injector sub-harness through the original harness clamps.





5. After the intake plenum is installed, make sure the "driver's sub-harness" is routed UNDER the IAA Valve. The injector sub-harness should not come in contact with any sharp objects such as hose clamps and can not be pinched in any area. Also, make sure the injector sub-harness is not making contact with the Throttle Valve. Tie-wrap # 2 injector sub-harness to the air-bypass hose. Do not place the splice connection in the original harness clamp. Make sure the connection is routed UNDER the IAA Valve.





6. Route the EGI main harness back in the original harness clamps on both sides. Replace any missing clamps.
