JDM engine will have the engine code H22A, tranny code for LSD is M2B4, if u buy front cut you can also tell if it's JDM just by looking at the stickers in the engine bay etc, they are all in japanese!
The complete wiring loom comes with a front cut but you wont use much of it anyway, you will only need the wiring and sensor connections from a few sensors that are on the H22A that arent on the f22b. The existing accord harness will connect directly up to the H22A, with that said, a couple of the wires need to be lengthened as the same sensors are in different locations on the H22A compared to the f22b.

What you do is disect the wires you need from the front cut ie, from the sensor to the ecu and once you have the extra ones you need, wrap them up in a new loom and feed it back from the engine to the ecu.
You only need one prelude mount to bolt the engine in, you use the 3 other existing accord mounts.

You should look for a 96 model front cut, i think they are fairly common although, i know that towards the end of 96 honda changed from OBD1 to OBD2 so find out what your car is and get a front cut to match.

I put a 6/96 OBD1 engine and ECU in my 94 accord. You will have to find ( for legality reasons ) a front cut the same age or newer than you vehicle.
