ok we have put a 92 dohc prelude motor in a 96 sohc prelude we also have the skunk2 harness for the ecu. ok were using the sohc wiring harness for the motor (maybe a problem). so the car runs like **** and misses all the time. i has a constant map sensor code and we figured that the sensor plugs wre mixed up between the: map, tps, and egr as they are all the same plugs. we have all the wiring diagram and still have no luck on this. can someone point me out here. please!!!! heres the wires wee have so far that could be wrong.
caps is main color, undercase is strip
MAP: (from left to right on plug) YELLOW/white, GREEN/white, WHITE/yellow
EGR: (from left to right on plug) WHITE/yellow, GREEN/white, RED/white
TPS: (from top to bottom on throttlebody) YELLOW/white, GREEN/white, RED/black
If these look as if they are in the wrong place please correct me. rember this is on a 96obd2 wiring harness. Please help. i have no choise but to post on a few sites so i can figure this out. its driving me crazy. thanks guys. if anyone has done this swap and can look at the wires please help! thanks again

Also will the F22 harness work for the H23?

Sik I'm at work right now, I'de need to be home so I can take a look at the wiring diagrams for the sensors you have listed in my bible.

Off the top of my head I do not beleive the F22 harness is compatable with the h23/h22 harness especially if it's OBDII VS OBI. I know you said you had the skunk harness but the ODII ecu is looking for sensor signals that your obdI engine may ot be able to supply due to lack of those sensors. But I'm not familar with what the skunk harness actually does so I may be wrong. The problem I'm going to run into is my bible is for and OBDI model lude only. You need to get your hands on a HELMS for and OBD II wire diagram. Someone on this board might have it and be able to scan one for you

I got the ODB I ECU though, everything is set up for ODB I plude I rewired the whole distribitor wiring for the harness. We got all the wire diagrams and we are doing what it says but it still will not come out of limp mode. Also the silinoid for the secondary runners in the manifold is that connected to the map sensor?

Hmm......I it might not be as simple as a mis-matched plug because for example if you have the MAP and the TPS mis-matched, you would be getting both CELs not just the MAP CEL. I don't know the colors off the top of my head either. Oh yeah I never used one of those ODB2 > ODB1 conversion harnesses either, so I really am not sure how the set up works.
