All the Info on Accord Swaps that I find seem to be OBD1 Accords with OBD1 H22A's. The only things I see for the OBD2A Accord to OBD1 H22A swap is a little blurb about relocation of the crank angle sensor; which I understand. So I've been doing my own research from looking at OBD1 Accord pinouts, OBD2A Accord pinouts, OBD1 H22A pinouts, OBD2A H22A4 pinouts, and comparing all of that to what I already know about the OBD1 car to OBD1 engine swap. Basically I'd like to share what I've found and would appreciate some confirmation or any extra info that I've missed.
-Here's a general link of informations that I pretty much find with every search: http://www.hondasociety.com/board/sh...ad.php?t=61998
-I'm not worried about the OBD1 ECU & pins , I'm just worrying about the correct OBD2A pins for the ECU. When I have it all wired properly, I will cross reference the wires of the OBD2A to OBD1 conversion harness, to make sure it is wired properly. I'm doing it this way in case the owner decides to some day use a USDM '96 OBD2A P13 ECU (because of emissions testing), he can just unplug the conversion harness and plug in the ECU.
-I need to add wires for the IAB (secondary "butterfly") and the knock sensor. VTEC is already wired up because it's an EX.
-From that link (as well as many many others), it says I need to swap pins for the O2 sensor heater and the EGR solenoid. From the pinouts I have been looking at, this appears only to be true for the '94-'95 (OBD1) Accords. My pinouts show that the OBD2A Accord doesn't have the EGR solenoid (as stated above), and the O2 sensor heater is in the same place for both OBD2A vehicles (pin A6). So from what I've seen, I don't have to swap ANY pins at the ECU, just add a few. (NEED CONFIRMATION)
-As stated before, I understand the crank angle sensor wiring. I also understand the internal and external coil issues.
-I also understand that I will likely need to lengthen some wires; IAT, MAP (firewall vs throttle body), IAC valve, O2 Sensor wires, ECT, and the alternator power wire.
This is what I've been able to come up with for this swap. If anyone can help me confirm that I'm headed in the right direction, or has any more info to share, I'd truly appreciate it. Thank you.
