Question on H23.

So i picked up another motor today. It's an H23a1 OBD2.
What do i have to swap to convert it to OBD1?
Here is what i have:
OBD2 H23a1
OBD1 Honda Prelude
OBD2 ----> OBD1 Jumper Harness
What else needs switched? I assume that it's the distributor from what i've read. Is that the only thing that needs swapped?

Re: Question on H23.

If you've still got your OBD1 H23 it'll be super easy. Pull your old one, swap your harness onto the new one, and replace whatever sensors don't hook up with ones from your old motor. The engine itself is exactly the same

If you need an OBD 2 ECU for an h23a1 send me a PM ECU has aprox. 128K miles on it.
