do i need to use a jumper harness when im using a 97+jdm h22a into my 97 accord ecu? or can i use my accord ecu with the h22a??? do i need to use the jumper harness for a 92-96 h22a??

 

I don't know what year if at all the Accord changed to OBD2b but you should be fine... Shouldn't need a jumper at all... I don't work with Preludes or Accords that much so i'm not positive but what you have should both be OBD2a and should plug straight in... Good Luck If you had the 92-95 P13 then you would need a OBD1-OBD2a jumper
