i just wanted to let everyone know that i just swapped a sohc zc into my 91 dx hatchback. I got alot of help with the wiring diagrams and such. but i just wanted to add alittle info that no one told me. USE THE FREAKIN STOCK DX HARNESS. It is much easier to wire mpfi to the exsisting harness rather than moding the si harness. Alot of people probably already know that, but its not posted. by the way, love the improvement.

 

doh, Of course man always gotta use the wiring harness that inside the car on the motor Good job on gettin her runnin tho any codes?

 

I did the same swap and you should ALWAYS use the stock harness to run the new engine, modifying it is better then anything else. I hate people who switch over complete harnesses.

 

Well it can be cleaner when repinning say an si harness but yea its deffenetly easier just adding the mpfi wiring, Hey you shouldnt "hate" Them its there headache
