I am doing research for an H22 swap into my 95 LX wagon. I have only found minimal info regarding my questions.

I have found a swap that is a complete H22 with LSD trans, H22 harness complete to ECU and ECU.

I know that it is basically a bolt in swap with minor modifications. I plan to use the Prelude intermediate shaft and axles for strength.

My questions are:

1- Since it has the complete wiring harness through the firewall to the ECU, is there any additional wiring that I have to do? My concerns are will the H22 ECU plug into the harnesses that go to the body to give the TACH, VSS, etc.. signals? Are these on a different harness that has to be custom wired?

2- Will the exhaust downpipe connect to the catalytic properly? am I going to have to have an exhaust shop make some adjustments?

3- I have also heard conflicts about the shifter cables, some say I need the Prelude shifter and cables, others say I can just use my stock Accord unit.

Any other info that you may have run into would be great!!! I'm super excited to get this done, but want to have all my ducks in a row before I just jump right in!!

I know this is almost a month old, but I want to make things clear in case others wonder the same.

1. Throw away the Prelude Harness you got there. Re-use your wagon harness. Add VTEC and VTEC Pressure Switch from those two back to the ECU since your's an LX(Non VTEC). Then switch Pin A6 and A11 cause they're backwards on the 5th Gen Accords. Just need to lengthen a few more wires so they can reach their sensors. You'll need to wire up IABs and Knock Sensor; since, you'll be running a P13 ECU I assume.

2. Exhaust won't fit unless you're running a Type SH header and downpipe which I heard will bolt right on. Otherwise, custom will required.

3. Accord shift cables works just fine. They're the same as Preludes.
