I finally figured out everything that was worng with my car and fixed them. Except for this. I have and OBD2 ECU from the stock automatic motor that was in my car, and it is running with and OBD1 motor. Yeah I know WTF. I am in the process of trying to find an OBD2 to OBD1 jumper for my new chipped p28 ECU. The problem is, there are two different types of OBD2 plugs. An obd2a and obd2b. Which one would i need to be compatialble with the new ECU, the A or B? The Chasis of my car is a 1999 EX. Any help is appreciated. Thank You.
