You'll need a OBD1 ECU and run the CKP sensor wire to the OBD1 distributor because the OBD1 distributor has the CKP inside the dizzy.

I heard, you'll need a OBD1 H22A Intake Manifold and Injectors as well. Not sure, double check.

 

all h series got the ckp inside the dizzy..i already ran the cables the car turns on but wit the stock ecu not wit the chipped p28 and i got the step down obd2b-obd1

 

dude there has to be something rong with the stepdown harness because I have the same engine in a 96 accord wagon with a p28 with prelude basemaps and I din't get no problems.make sure that all wires match on the stepdown harness

 

Not the OBD2 H22s. I was told they are on the oil pump housing unlike the OBD1.
