    I have a 95 gsx that I have just put a 6 bolt in. Im keeping the 1g coil pack and I do have dsmlink as well. I also have the cas adapter harness connected. Before I try to start the car I was wondering if I need to swap the spark plug wires ?

    Swapping plug wires comes down to which ECU and CAS combination is being used. The wiring/harness does not change the signal the sensor is outputting, nor how the ECU receives it unless it is wired incorrectly from the start. In short:

    If using a '95-'96 ECU and '95-'96 CAS --> no change.
    If using a '95-'96 ECU and '97-'99 CAS --> change spark plug order.

    If using a '97-'99 ECU and a '95-'96 CAS --> change spark plug order.
    If using a '97-99 ECU and a '97-'99 CAS --> no change.​

    That is all that this picture is saying. When the original order in any normal case is 4-1-3-2, then if a change is required, it will become:

    You can also swap the ignition wires at the ECU. I have done that on a 99 with a 95 eprom with ecm link when going to coil on plug with a 97-99 spark tech kit.
