I'm putting a OBD1 GSr in my 97 dx EK. It has the blox mani is the only difference from a stock GSR. I will be running a S100 P28 ecu with a jumper harness. here is my problem. I went to go buy a 96 civic EX manual engine harness and it had an extra plug up by the drivers side shock tower. That was the only real difference i could see. He said once i buy it, its mine. There is no extra connector on the car except for that 1 wire thing with the cover over it. Anyone, know what this is for? dont want to but this thing and then be some weird harness that wont work. I searched but could not find anything like this.
Thanks
Rick

 

Can't you use your 97 dx harness instead of buying a new one? Or are you saying that your car is automatic right now?

 

u can use the same harness i used mine

 

maybe the guy is sellin u a obd2b harness

 

I was going to say the same thing. But I don't know the differences between 2a and 2b harnesses so I didn't say anything.

 

yes he can only have to add a vtec wire and knock sensor. inless hes auto now and then i have no idea?
im pretty sure the car is obd2A

 

car is obd2a. I sold the dx harness with the stock swap. the obd2b cars have the "A" harness as part of the inside cabin harness and the obd2a cars hae it as part of the engine harness. Just trying to figure out what this extra plug is.

 

Quite frankly I wouldn't worry about it. The EX harness will work fine, I wouldn't be too concerned.

 

well i Just Had That fixed i got a 99 dx and i was swapping a 97 single cam non vtec...if you have an extra wire in the cabin thats a obd2b harness u need the same one as your car year..i was trying to run the old obd2a on the 99 which would not let you turn it on
