    Can anyone assist me with pictures or other websites on this because i've searched way too long and hard and haven't found much, if anyone can help, i would really appreciate it. Ok, i did a obd1 jdm H22a swap on my 92 prelude that didn't come with vtec. It came with an F22 engine. Anyways, i finished the swap and everything works, its drivable and all, just that the KNOCK SENSOR, IAB, and VTEC isn't wired up and thats what im having trouble with, i need to know how to wire it up or get some kinda info on how to do it. Thats all that i believe i'm missing out on. Any help guys?

    Hey guys, just to let you know, these sites i listed here are very helpful and i got all the things done by myself. Vtec works regularly and all. Don't forget to invest in a soldering kit cuz it sure enforces a simple wire connection.

    did you have to swap the distributor or fuel rail at all?

    I went with the USDM fuel rail and distributor/external coil because it was an easy swap over. The JDM distributor doesn't come with an external coil and needs wiring done. Also, use the H22a injectors while you're at it.
