i have a '93 civic sedan dx with a d15b7 in it now, which is shot. i also have a 95 civic coupe ex with a d16z6 in it, but is wrecked, every thing is still there. what would need to be done to swap the z6 into the car that has the b7 in it? i know the motor will go right in, but the wiring is different. can i use the engine harness and plug it right up? or, do i still have to wire it my self? is my car already wired up to the engine compartment? or, do i have to go all the way to the ecu? i aint no mechanic, but i can do it with the right info.
