Method 2 Wiring Diagram for 95-96 ECU's

95-96 Cars ver1 95-96 Cars ver2 97-99 Cars

This harness is now for sale if you do not wish to make it your self. See the main 6 bolt swap page.



Due to the inverted Cam signal, injector trigger wires will need to be switch on 95-96 year ECU cars with this wiring diagram in order to bring the signals back into phase.  The difference is subtle, but the motor will start easier,  provide smoother idle, and have less hesitations during mild acceleration.

Use the following diagram:

When removing the pins on your ECU wiring harness be patient and delicate.  It requires no force to remove the pins.  Consult the diagram in the front of your electrical service manual regarding the proper way to inspect and remove pins.  You will need a tiny jewelers screwdriver, (1/16 in) to release a plastic catch holding the pin's in. Use a flashlight and take a good look at the harness before beginning.

Green: Pin 1 is now 14
Green w/ yellow stripe: Pin 2, is now Pin 1
Green w/ red stripe: Pin 15, is now Pin 2
Yellow w/ black stripe: Pin 14 is now Pin 15

The spark coil signal is inverted. Looking at the coils, label each wire A,B,C,D. Change the spark plug wire locations: A is now C, B is now D, C is now A and D is now B. Another way to do this is to change the trigger wires to the coil, (3 wire triangle plug, next to the igniter).  Switch the two blue wires.  One is blue with red stripe, the other is blue with black stripe. The third wire that remains unchanged is black with white stripe.

Don't take shortcuts in the quality of your connections.  Solder everything.  Use shielded cable if possible. Do not use wire taps.
