Searching for this procedure is a little vague so I thought I'd write it up for the new guys.
Ok there are no "extra" wires or anything to add, other than the normal H22 swap wiring. If your H motor is obd2 you will need the following to make it work in your obd1 car (90-95 Accords):

1.obd1 ECU(P72,28,etc..)

2.obd1 fuel injectors. (345 peak and hold type. ) Now in my expeirence these are hard to find used and will be the hardest item to find for this swap, There are no definite ways of telling from the outside appearance if the injectors are from an F22, H22 or H23. So make sure you trust the seller

3.obd1 alternator. The plug on the alternators differ. (You can use your Accord alternator.)

4.obd1 distributor. obd 1 dizzys have internal sensors that the obd2 dizzys do not.(cannot use the accord dizzy)

and thats it!! simple right. Well maybe not. this swap will cost you more than a normal H swap cuz of the few extra parts you will need. The only advantage ogf an OBD2 swap is that you generally get a motor with less milage or you get an H22 type-s sir spec motor. No you cannot generally use the SH tranny. (much labor and fabrication involved.) You can use a type SH motor but again the labor is a little more involved. (for instance you gotta tap some holes into the block!)

 

cool

 

Thanks man, That's all I needed to know!
