    thanks

    nfn15037 says to use a 97-98 ITR ECU with your swap. B)

    Edit: It's still a P73 ECU but it's an OBD2a instead of what you are trying to use... and OBD2b (which also has an imobilizer built into it). You'll see that a OBD2a one will have the right plugs on the side for your wiring harness.

    yep-- you're trying to use a 98+ usdm b18c5 itr ecu on it.

    see what you got here:
