I have a 2000 Integra GSR and recently removed the turbo kit. Im going back stock so i know the 2000 GSR's ECU is the p72b....If i have a stock p72a04 ECU and i purchase a complete p72a engine wiring harness will that fit up with the p72a04 ECU that i have or do i need to purchase the p72b ECU since its a 2000? Any help would be much appreciated. Pm me if you can or even txt/call me 864 567 0608..thank you
