First, I have searched and cant find this exact info. I have a 96 prelude si w/ h23(obd II). I'm planning on doing an h22 swap soon. I found a 92-95 obd1 jdm complete swap for a good price. It comes w/ everything encluding ecu and harness. The problem is that the harness is for right hand drive. Will my current harness work? If I have to use the new harness what mods do I have to do to make that work? Last one, Any other chages other that the ecu for the obd1 to obdII change.Thanks

i dont think you searched hard enough. anyways, yes you can use your stock harness but you will have to wire vtec and you will need a obd2 to obd1 conversion harness.

 

The harnesses are the same on both USDM and JDM motors; however you will need to swap over the fuel rails and use the old H23 fuel rail.

93+ Preludes all were pre-wired for VTEC.

I would find out the laws regarding converting an OBDII car to OBDI. In my state, it is illegal.

 

i dont know about in NJ, but here in NC i had to get an obd2 computer to work enough for me to pass inspection....

this info has all been posted up before....

oh and i have yet to find where my car was pre wired for vtec.....

that i didnt know. learn something new everyday.

 

Would I have to wire vtec if I went with an h22 that was from 96+?

 

My 94 s was NOT pre-wired for vtec. Trust me i know.
