Hi, have a Civic EG3 -93 and is about to swap to D16Z6 engine.
Got the harness from the same car I took the D16Z6 engine from and also have a P28 ECU with booster control laying around.
This should be plug n play considering I have the original harness from the D16Z6 engine right?
Thanks for a great forum btw.

 

There may be a wire or two for VTEC you'll need to run from the ECU to the shock absorber tower to connect with the engine harness you got. Your EG3 wasn't carbureted though, was it? Because then it's a lot more fuckery.

Lots of posts on this topic though. Check the FAQs.

 

for some reason the 1995 civic I got came with a d16z6 so im sure its possible.
