So I got an obd2a->obd1 conversion harness since i'm doing an obd1 h22 swap into my 1998 integra. Anyways and I had a question, I don't have a halms manual, I try to find most my info online and I was wondering do I have to change the wires to match the pinouts on the p13 ecu for my h22, example like rewire my IAB to match the IAB pinout on the ecu and do this for every wire and pinout, or does it already come prewired to do all this? Thanks for any help!

When you buy a conversion harness it moves most of the pins for you, but you are going to have to add wires to your harness due to the fact that civics dont have IAB's or Egr systems (unless its a vx). I didnt even bother with p13, I used a chipped P28 to save myself the hassell of the egr system. You could just wire your iab's on a rpm activated window switch, or use your vtec signal to activate them. Hope that helps.

I have an integra, so would it already be wired for IAB's? I don't have some EGR stuff from a prelude so my EGR's not ganna work, will I still get a CEL if I don't have the EGR solenoid and valve? Thanks for any help.
