I've got a 99 prelude sh and i had a h22a engine in it, but i just got a 95 jdm h22 engine put in it. And the new engine has an internal coil but the old one had an external coil and the car won't fire at the coil so i dont know what i need to do to make it fire. And I dont know if i need to rewire anything. And the internal coil distributor won't plug straight up to the harness from the car so i don't know how to fix that. Please help.

 

the thread for the conversion is dead...i know this isn't what you were looking for, but it may have some help in it with the distributor. i haven't read through it to see how thorough it is, but here you go...
