    It should be the 4CU unit. There isn't fault reader capability on the 'flapper' system, it's all probe work on the components.

    You can do all the other things you mentioned with the hotwire ( 14 CUX system - D1 V8 fault reader or connection )

    And you can swap entire systems if you happen to find a later model wreck.

    I'm reasonably sure OBD plugs started in model year 95.

    I found the manual-on-cd in the shop section the easiest way to do that.
    Also, google 4cu ecu and a fair amount of stuff is available.
