ok.. i have a 2000 jdm gsr obd2b engine harness that came on the motor. i purchased an obd2a 96-98 civic ex 5spd engine harness to use with the 97 obd2a gsr ecu i bought. i am trying to adapt the 96-98 civic ex engine harness to the obd2b gsr engine harness but there are so many MORE plugs on the civic one than the gsr one. is there a guide or something for me to be able to know what plugs to cut and splice?? very confusing. can i go by colors or something? cant use a conversion harness because my car is obd2a. everything is obd2a except for the motor itself and i need to pass smog
