    Could someone at least just mention what connections does the dizzy use ?

    I got an obd2 sheet colour coded with the connections, but there are so many here i dont know which ones of all these does an obd1 dizzy use.

    Can anyone mention them ?

    when i did my swap i looked at the colors from obd1 to obd2 all were the same
    i just pulled all pins from obd1 and made a diagram
    compared to obd2 and they were all there so i just pulled all pins out of obd2 plug made diagram and put obd1 plug on obd2 dissy every thing works

    Did the conversion .. everything works greta on the obd2 ecu. Now swaped to obd1 ecu and onece again! .. get the rev prob. I`m sure everything is wired correctly .. Why the hell is the p28 not reving over 5000.

    I lost hope ..
