My buddy has a 89 Honda CRX DX. It has a swap in it with D16z6 block and a D16a6 head. What harness should be be using for this swap? If there is any plugs that get eliminated, or items that need cut and spliced please let me know. My friend is new to the honda game and im a b-series civic guy so im trying to help him as much as possible.

 

when doing a swap, always use the engine harness that originally came in the car and make the necessary wiring changes to it

 

yea thats what i did with my swap but like i said i dont know if crx's and d's are the same. he has both the stock harness and a harness from a crx SI. which one should he use?

 

you use the dx harness and convert to mpfi.

 

it was converted for the injectors. for some reason the code for the IAC valve it being thrown now.

 

probably have the wrong connector plugged into it - should be 2-wire connector with blue/yellow and black/yellow wires

 

il have him check that out. i think im just going to have him take the harness to a shop. anyone know of shops that are good with harnesses? im in PA

 

Has he done the full dual point to multpoint conversion??
Its not just injector wires!

Well the eacv could be not hooked up right or could be bad on the new motor

 

the guy my friend bought if from took it to a guy who did the harness and when it left the shop it worked fine. then the guy my bud bought the car from fooled around with some stuff and effed it up. long story short my bud is taking it to the guy who originally did it to fix the mistakes made.
