    Was wondering if anyone knew what wires do i need to change when installing an 89-90-91 engine harness in an 88 si chassis car?

    I know on the drivers side that the plug on the 88 si harness is a 6 pin connector and needs to be repined into the 89-90-91 harness according to color.. On the harness i am left with a blue and black/yellow wire (which go to the EACV and FAST IDLE circuit) extra on the 89 engine harness.

    Also what pins change on the pass. side plugs....

    Just wondering if anyone knows the secret so i dont half too dive in the schematics!
