    yeah but count the flashes on what?? there is no LED indicator on the ecu, and the CEL stays solid??? so thats why im wonderin how im suppose to read the codes.

    i thought you said it HAD the light and you didnt know how to read it. wow thats my bad. from what i've read thus far it seems people are saying to jump the D4 ecu pin to ground, and it makes the ecu start spilling out codes by flashing the cel light.

    heres the obd1 codes btw.


    OBD1 Trouble Codes: Code 0 and 11 [COLOR=blue! important][COLOR=blue! important]Electronic [COLOR=blue! important][COLOR=blue! important][COLOR=blue! important]Control [COLOR=blue! important]Module[/COLOR][/COLOR][/COLOR][/COLOR][/COLOR][/COLOR] (ECM)
    Code1 Heated [COLOR=blue! important][COLOR=blue! important]oxygen [COLOR=blue! important]sensor[/COLOR][/COLOR][/COLOR] A
    Code 2 Oxygen content B
    Code 3 and 5 Manifold Absolute Pressure
    Code 4 Crank position sensor
    Code 6 Engine coolant temperature
    Code 7 Throttle position sensor
    Code 8 Top dead center sensor
    Code 9 No.1 cylinder position sensor
    Code 10 Intake air temperature sensor
    Code 12 Exhaust recirculation system
    Code 13 Barometric pressure sensor
    Code 14 Idle air control valve or bad ECM
    Code 15 Ignition output signal
    Code 16 Fuel Injector

    It should be on the far right side by the glove box, above the kick panel, assuming you have the switch. On some chassis it seems that this 2 prong connector is actually in the engine bay. Possibly by your driver side shock tower, or motor mount area.

    If you can't find a plug to use, like i said you can just jump D4 to a ground. I haven't personally done this, but others have.

    ok not to sound like an asshole now but which plug is the D plug?? it only has three plugs in the back of the ecu which i though was A, B, C?? and i found the plug by my shock tower jumped it and the CEL stayed solid??? does it have to be started or should it throw codes with the key just in the on position???

    i realize this isnt for your ecu but you get the idea. the connectors are A,B, and D.

    GSR/ B16A OBD1 ECU pin out

    As far as reading the code like i said i haven't had to do it so i'm not certain. you would either have the car in the on position and jump the connector. or possibly you leave the car off, and then turn it to on with the connector already jumped. i'm not entirely sure.

    ok now im confused. do i do the d4 on the jumper harness or the d4 on the stock harness??? and if its the one on the stock harness no wire goes to the ecu from the d4 plug?? if some one has a pick or anything that would be great. thanks again.

    nah he said that it was obd0 and he wired it obd1. plus he hacked alot of shit up. actually im not sure if he did but its pretty hacked up!!! still dont get it. i might just get a dx wiring harness obd0 dizzy and resistor box ecu and just go back obd0
