I'm in the middle of an H22 swap for a friend: He wrecked the Prelude and decided to put its engine into an Accord. Every bit of information and FAQ I've read has no info on wiring for this later model engine swap since most people use earlier or JDM engines.

The engine mount differences between earlier and later H22s were mitigated with earlier OE style mounts, however, the only wiring that I have is the stock Prelude engine harness, stock F22 5th gen Accord engine harness, and the chassis wiring out of the Accord.

I've spent over a dozen hours searching forums and search engines trying to find accurate information, and all I've come across so far is

a. A guide I'd need to pay for
b. random conflicting tidbits about theft immobilizers?
c. other random conflicting information on forums.

Any help, suggested search terms to use, or links, would be greatly appreciated. I do have PDF's of all relevant FSMs already.

Thanks for your time.

Does he have an EX or LX/DX Accord? As that does matter with the harness. Use the Accord's and modify

I'm personally not sure about the immobilizer, but if his prelude had an immobilizer he'd need a OBDII USDM P13 without an immobilizer or a chipped computer

It's an EX with the F22B2.

The code on the Accord's ECU's label reads 37820-P0J-L10

Prelude ECU's code P5M-L04

You'll be using the Prelude's ECU, Accords don't have an immobilizer, the prelude's ecu is the concern

I thought maybe the Accord's ECU would help illustrate the type of connector: they are both obd-II ECU's.

Ah gotca, if it's a 96 + Accord it'll be OBDII.

You'll need to worry about adding the knock sensor and one other (can't recall) but those should be listed in the FAQ's

I'm guessing you want to keep it OBDII so like I said you'll need to look into a USDM OBDII P13, but from what I've heard they're pricey.
