    NO. Those 2 harnesses are NOT the same.
    Injectors don't need to match anything (obd0 uses a resistor box, OBD1 and OBD2 do not)
    B16 and GSR distributors are both TD-44/68. Same thing.
    You should be using a P72 if you're running a GSR with IAB's (intake air bypas valve)

    Those are the right answers. If you don't have IABs, run a chipped and tuneable OBD1 ECU if you want the best performance.

    And why do you need an HF CRX harness? What is in there now that recently ran the car? Dont replace things that don't need to be. You can't buy your way out of most problems.

    ok thats what i was hoping to here i need the harness becasue i just got the shell the dick before me pulled the harness out, and the harness i have on my engine is the 91 teg wont fit because i have that square plug on the one side or the car, i figured i needed the p72 someone tried to trade me for a b17 ecu but i didnt think it would work, i have a obd2 p72 i need to either sell or trade for the one i need

    The general rule of thumb is

    To run obd-0
    , use obd-0:
    ECU
    Distributor
    Injectors

    To run obd-1, use obd-1
    ECU
    Distributor
    Injectors

    etc.

    Then you've got to consider whether or not the engine harness your using can be adapted to run newer model parts(obd-2+ on an obd-0 harness, etc).

    Also another thing to consider is which type of injector you can or cannot run in your car... whether it be Peak 'n Hold, or Saturated injectors.


    ... Just some things to freshen your memory.

    Not all injectors are saturated.
