Hey Wagsaccord!!!!!!!

I WAS THE ONE THAT IS GOING TO SWAP AND H22A IN TO MY 91 ACCORD!! BUT I HAVE A QUESTION YOU SAID I NEED THE PIN OUTS OF THE H22 ECU BUT I REMOVE THE ECU OF MY ACCORD AND SWAP THE H22 ECU IN THE PIN OUTS OF THE ACCORD AND THEY FIT IS THAT OK? BECAUSE IF THEY ARE THE SAME THE ONLY WIRES I HAVE TO INSTAL ARE THE ONE OF THE VTEC KNOCK SENSOR AND THE OIL PRESSURE OF THE VTEC!! OR IM WRONG?????? ANOTHER THING I DIDNT START THE ACCORD WITH THE H22 ECU!!!SO CAN YOU HELPME OUT

Sorry if I confused you. Both ECU's have what are called pin-outs, just a name they use to identify the wires coming out of the jumpers. You can't just plug in the H22 computer to the Accord wiring Harness, you have cut the Accord cannon plugs (jumpers) off and then you use the cannon plug that comes with the P13 ECU and then you have to match the wires up, and it isn't based on color-matching, its based on "pin-outs". I hope I'm not confusing you. If you need me to break it down, just let me know, I'm not trying to insult your intelligence, I just have a hard time explaining things.

There will be some wires you don't even use. Out of the ones you do use, there will be a few for the VTEC and the VTEC Oil Pressure Reg.. Run your wires from the VTEC and the VTEC OPR staright down into the firewall and wire em up to the identified pin-outs.

If I remeber right, my VTEC wires were red and they wired into the 2 brown wires coming out of the ECU, I think they were brown could have been the otehr way around, I could be wrong as when mending these wires the colors never match, thats why pin-outs are important.

Understand that this swap is not plug and play. The Accord wiring harness that plugs into the F22 ECU are not the same as the ones that plug into the H22 ECU. You have to cut ALL the wires and mend them to the H22 wiring harness. This is why its important that you get the schematics so you can wire them right using the pin-outs. Its sounds like a pain, but reall its cinch, a monkey could do it.

hey wags accord thanks for the advice but yours is a 5th generation and mine is 4th so they are different wiring harnesses bacause i was told in 4th accords the swap was easy than on 5th generations! I think im confused or what do you think of this page http://members.aol.com/accorddrv/h22.html and another thing do you know where can i get the wiring maps of the ecu h22 and the f22? cause i went to the dealer and they say they dont sale it and i went to auto parts to check in the hanes and chilton they dont have on their books.........how did you get them?if you have the h22 wiring map can you sale it to me????????

Wiring should be very similar, but you need to get those pin-outs. I unfortunately don't have any as they were never mine to begin with. I'm not sure where my boy got them from, but I will see..
