Icon2 OBD1 CAR TO OBD2 H22A SWAP

I have read through many pages of wiring tips, explanations, and examples of wiring write-ups. And still i am unable to locate any help to what seems to be my own personal issue with my swap.

details:

1992 Prelude

car originally came single cam f series, non vtec... external coil
swapped in an OBD 2 longblock with obd2 distributor that came with the longblock
using obd1 ECU

what i need is a some help with the wiring to convert the obd2 engine and distributor to work with the obd1 stock engine harness and ecu using the external coil set up...

what i really only need to know is can it be done and run correctly
and if possible the wiring pinout diagrams.

the distributor on the motor the obd2 external coil has the two plug set up
first plug is the two wire plug the blk/yel and the solid blue
second plug has the 4 wire plug... green, yellow, yellow/green and black

can anyone help me or guide me so i can assemble a sub harness myself to plug and play the obd2 dizzy into my obd1 stock harness?

i will also need some help with which wire is which coming from the sensors on the oil pump which i also realize have to be wired in also.

any info or suggestions will be greatly appreciated.

You should be able to use the F series distributor on your engine, then you can just plug it right up. Pretty sure F and H distributors are the same.

what youre gonna want to do is get the wiring diagrams for both distributors and basically cut and splice all the wires or repin them. you could also just get a complete obd1 engine harness that came from a h23 or h22, as the distributor plugs might be different from an F-series engine, i dont know off hand. I have a 93 prelude with an obd2 firewall/fusebox harness jumped back to obd1, obd1 engine harness and i have a obd2 h22a, and it runs great.
