    Some will find this useful.Though I am not sure about the ECU supporting a IAB from a GSR,since there isn't a OBD 0,GSR.hmmm.....any thoughts?

    That is the best explanation for a pinout that I've seen. I just wish that you had one for H22A, but that gives a guy a way better idea. ;)

    H22 in a 4th gen is not a good idea.

    If you are putting this in a 5th or 6th gen, hit up www.hasport.com for more info.

    You just add 2 wires.

    Pins B10 and B12 are empty. Unused pins can be taken from B2 or B11. Sometimes there is a unused wire at B12.
    Cut orange and white wires off at C1 and C2 and connect them to wires added at B10 and B12. Orange-B10. White-B12

    Run wires from C1 and C2 on the ecu into the engine compartment. Label these wires for later use.

    Cylinder position sensor

    Connect C1 to blue/green wire on cylinder position sensor plug.
    Connect C2 to blue/yellow wire on cylinder position sensor plug
    the rest of the wires are color matched ur dx to the si wires
