Hi i just got an F20b and right now im attempting to hook it up to my harness. The lude i am putting it in is a 4th gen specificly an s so it came stock with an F22a1 single cam. OK now heres the question i bought a harness out of a 96 prelude vtec thinking it would just plug in. and it doesent. all of my research says that the f20b is obd 1 even though it was made in 98 and it has black injector clips. what kind of harness do i need? i still have the harness that came with the engine but it was cut. do i have to solder on the plugs that wolnt work? i will take a couple pics of my plugs to see what you guys think. Thanks

you will need to modify and use your existing harness. Get an OBD1 distributor(dizzy), run vtec wires and knock sensor wire unless you are running a chipped ecu then you can bypass the knock sensor. probably missed a couple of things but those are the main points.

 

well the stock harness was cut or are you telling me to use the f22 harness?

 

use your f22 harness. when I swapped an OBD2 H22 into a 92 accord,I used the F22 harness. you may have to lengthen the alternator wires and also use the F22 alternator.

 

ok thank you for the help
