what all need to be modified? what year h22 to buy? is there anything in the engine bay that needs modified?anyone here convert wireing harnesses?

 

If you want it to be easy, get a H22a4 97-2001 H22, get the P5M obd2 ecu, and everything is plug and play. I can help you with the swap if you need help. Ive done my share in a EG, its not much different in a EK.

 

when you say plug and play you mean the harness doesnot need to be converted or modded?

 

even if you go all obd2 there still is some extensive wiring to be done.

I have done 2 obd2 Ek h22 swaps. and IMO the easiest/best way is to use a NON external coil dizzy. OBD1 ecu chipped and socketed ( no Speed govenor, No egr, no knock sensor ) . All that will be needed then is minor wiring depending on the model of the car ( ie: ex, dx, cx etc: )

 

lol well ok u gtta extend the alternator wire. And whatever you cant stretch far enough to fit the motor. when u get the motor sittn in front of you *b4 u put it in* take the harness and plug it all in and test fit it. Then leave the harness on and drop the motor in, makes it so easy.

Whaterever little wires dont quite reach u have to extend.

As far as the alternator goes, your best bet is to find a prelude or F22 harness, and cut the loooong alternator wire bunch off, and match em up.

Ofcourse you can do what jake said as well. get a P28 obd1 ecu for example, and have someone run a map for a H22, and dont worry about speed limiter and all that schnick schnack. If you get a internal coil dizzy it would plug right in. If you do end up with a external coil. There is a wire you have to plug into the engine harness side of where the Dizzy plugs in. I believe its a green wire on the dizzy side. Wire the blue wire from the External coil to it, and cut the yellow black wire off and cap it, and run the black wire to a 12v power source like the fusebox.

 

hey man, i want to swap a h22 into my eg. i have everything except for the wire harness. you know where to get one and how to modified for it to work. if you could help me out. or call me at 813-389-9259 my name is ty. thx man.
