Does anyone know how to wire an H22 in a 4th gen. accord??? If so let me know, I really need mycar on the road. Thanx.

 

plug the harness in
thats it
its nearly a perfect fit
add the 2 wires and a ground for vtec, add the wire for knock sensor.
its probably the simlest wiring for any honda swap.

 

you need 2 more wires for the IAB control solenoid.

but it really depends on the engine you have. if you have an H22A1 with the OBDI engine harness, you're set. if you have the H22A4 with an OBDII engine harness, there's a lot more wiring involved.

you'd be best off either using the H22A1, or converting the H22A4 to A1 specs for a simpler drop.

lastly, the A1 uses peak and hold injectors with a resistor box. the A4 uses saturated without of course a resistor box. i cant remember which type of injector the 4th gen Accord uses, so you may have a small wiring fiasco in that respect also, but nothing difficult as long as you know what you're doing.

 

I have a h22a1 supposed to be jdm but hondamotorsonline dicked me over i think, but the prelude harness doesnt plug into my car harness and if i use the accord harness on the h22 theres 5 things that have have to be wire manually to the ecu. And i cant figure it out. Do you guys have any idea what i can do?

 

the prelude harness does not fit the accord body, not supposed to.
on my 4th gen the harness fit near perfect. i had to add the 2 wires and a ground for vtec, had to switch 2 plugs for oil pressure sensor and EGR lift sensor, then add a pair of wires for the IAB (ff2a6 has this already though)

total time to wire it up...1 hour.

 

find a friend who knows what he's doing, offer him a case of beer and let him wire it up for you.
