Hey guys, I have what I believe to be a simple question for the pro's... I have a 1992 Civic VX. It is wired for V-Tech already even though it's a poor excuse for V-Tech. My question is, if I wanted to throw an obd ii gsr in there, would I be able to keep the same wiring harness since it has v-tech already? Or is there a real difference between the harness of obd I and obd II? An extra plug maybe? I truly don't know... But if I could just plug and play that would be some amazing news to hear... So go ahead guys, fire away.

 

First off, VTEC. It's variable valve engagement, not a portable home phone.

It would be *mostly* plug and play, but you would have to modify a few things. VTEC would be the easy part - your O2 sensors would be more complicated to wire than VTEC would be. It would be more logical to get an OBD1 GSR, though.

 

Obviously it would be easier to do a 95 gsr. But finding that would take 3 times longer. And so I put a hyphen, big deal. So the "vtech" plug makes no difference between the harness'?

I don't want to stray too far off topic, but for educational purposes:
It's not about the hyphen. It's about the actual word. VTEC vs VTECH.

 

OMG THANK YOU CO671. Did you do this swap already?

 

lol no... my Civic has a stock d16y7 . I just googled...
good luck
