AMEN!!! SEARCH!! There is a thread at the top of this forum called ***Post Links to Helpful FAQs So We Can Get an Archive Going***. Do you think you are the first person to do this swap? If you answered yes, then you shouldnt ask here because you think no one has the info. If you answered no, then you shouldn't make a new thread without searching the archives, new posts, and for god's sake the FAQ thread cuz wouldn't ya know it but there is a shitload of info in the FAQ thread about this swap. And if you need even more info then *gasp* click on the search button...if you can't figure that one out, then click here *very helpful* - https://honda-tech.com/zerothread?id=749544.

I am going to help you this ONE time and ONE time only so maybe you will search next time. I clicked on the FAQ thread and 5 posts down Poison posted:

H22A into Civic information:
MERGING OBD1 CIVIC HARNESS TO H22A ENGINE:
- Take off and mark every single harness connector on where it came from/where it goes from both H22A and stock civic engine. Make sure you label them of where pulled the plug from! This will save a TON of time!

Mount Civic harness on H22A and measure/modify wire to be lengthened/changed as follows:

- Change fuel injector connectors to H22A type and add resistor pack from H22A harness to Civic harness (see diagram on page 4)
- Extend Alternator wires to reach the H22A alternator (match the pinouts)
- Lengthen wire that goes to the starter solenoid on starter
- Attach reverse light sensor wire to the new H22A reverse light sensor wire

O2 sensor (CX only) add 3 wires to O2 sensor and follow o2 wires and change to Prelude O2 sensor connector. And wire the following:

- WHT/RED wire goes to D14 which is O2 Sensor Input
- ORG/BLK wire goes to A6, which is Heater Control
- GRN/WHT wire goes to D22 which is Sensor Ground
- YEL/BLK wire goes to A25 which is Sensor voltage

VTEC wiring: This applies to DX,LX,CX models only in 93-95!

- Wire from the VTEC Solenoid to the A4 pinout at the ECU. Add the pin to the shock tower harness, and female pin at the female shock tower connector.

Knock sensor wiring: (mounted at the rear of the engine near the cylinder head)

Air Intake Bypass solenoid (secondary butterflies)

- Sensor voltage to the A25 pinout (or splice into the Yel/Blk wire connector at the driver shock tower harness.
- ECU Signal leading to A17 pinout on ECU

EGR (Exhaust Gas Recirculation) System: Applies to all model civics except VX

- EGR lift valve solenoid – sensor voltage (A25 pinout) & ECU signal to A11
- EGR lift sensor – sensor voltage (A25 pinout), ground (D22 pinout) & ECU sensor signal to D12

MOUNT KITS AVAILABLE:

- HASport mount kit
