i already did a search and i just want to make sure im gettin the right idea and if my idea will work........first question.......will my stock y7 harness plug up or will it not fit because of the different obd systems........and if i keep the obd1 dizzy starter and injectors can i just cut and splice to obdII wires to make everything work smoothy.......and after that use a obdII to obdI jumper harness to use the obdI ecu.......hopefully what im sayin is clear any help would be great thanks a ton

You will have to reuse your stock harness on the h23, but it doesnt come close to just plugging in.

You will need to change some plugs to obd1 as well as lengthening quite a few wires (like the alternator). Also you need to wire in an injector resistor box.
And if your car is a dx or cx, you will need to change from a 3 wire Idle Air Control valve to a 2 wire.

Then you can use your jumper harness to plug in the obd1 ecu.

Your best bet will be to sit down with electrical diagrams for both motors.
