swapping original f22a+auto with h22a+auto.. which came with ecu but wiring is a little different.. has anyone done this, is there a diagram that can be used, or another ecu/harness i should get?

 

from my search so far it sounds like use the original ecu and wiring as much as possible and add wires for solenoid, pressure and knock sensor..

 

That swap has been done a lot. I posted a link to an H22 swap guide in the DIY section a while back. Google search and searching this forum will help you to get organized.

I think that you will need the ECU from the prelude, because the stock 93 did not have vtec. You will want an ECU from a pre-96 prelude, so you can stay with OBD1.

 

I found that guide but it was for a 94, thanks though I will keep looking

 

I think the H22 swap is easier with the 4th gen (90-93) accords, because the honda mounts will work without modification.

I think the swap should be very similar to the 94 swap. I am not sure what parts you will need from the prelude for a/c, power steering, alternator, etc. There is a site called hondaswap.com that has a lot of info about this.

 

yeah absolutely no luck online other than what i said in post#2 but i do have all of those parts

 

Google:

cb accord h22

or
cb accord h22 swap

The first few hits give some information. You'll just have to piece it all together. If you want to help the forum, keep track of what is needed.

motor seller says: you cannot use a jdm engine wiring harness , you will have to use your usdm engine wiring harness no matter what engine you got in your car and use maybe ur injectors as well

which makes sense.. i'm gonna figure this out one way or another and let it be known! heh

 

cool that checks out thank you again PAhonda!

 

You do have to use your stock harness. And you will use the ECU that came with the engine.
