Hey, i am getting a JDM B18C in my 94 civic EX. im not sure if the B18 is ODB1 or ODB2 tho. if its OBD2 can i still use my civics engine harness, or do i have to buy a USDM OBD2 engine harness. Also, can i just use my P28 or should i swap out for the P72? is the knock sensor really important, since i think that is the only difference. thanks,
Kaleb
