    should be a straight swap. both cars came with f22's in them. I'm assuming that's what you're pulling out of the accord. The prelude could have came with one of 3 engines in it f22, h23 or h22. The prelude will have an obd1 engine where as the accord of that year will be either obd1 or 2 depending. but to the best of my knowledge it should be a straight swap

    As stated above should be a strait swap over... the only thing i can think of is if ya engine is an OBD2 then the o2 sensor mite need some diffrent wiring... other than that if you have an H23 / H22 trans I would put that on the F22 as they are better Trans IMO... but thats me

    ok the motor is in and mostly hooked up
    i have two connectors left over. they come off the engine harness and go back in the driverside firewall on the 94 accord
    there ar no matching plugs on th 92 prelude
    does this mean i need an obd harness?
    thanks in advance

    ...Both should be OBD1.

    Do you have a picture of the connector?

    sorry no pics but its two grey connectors one is 8 wire they go back into the drivers firewall from the engine harness
    most of the wires are yellow and green if that helps

    The 8 wire one is just yellow with black stripes? If so, there's supposed to be a "plug"(it really jumps all the wires); it just sits there. I'd have to check on the other connector(I have a 92 Accord and my sister has a 94 Accord; from what I can recall the wiring was similar).
