So when I swapped my H22 into my 1989 CRX Si, I bought a harness from rywire. Now that my friend wants to swap a H22 into his 1989 CRX DX, (yes we know it has to be swapped from DPFI to MPFI) we are looking at harnesses and he asked me if instead of messing with the wiring and what not ourselves, if he could just buy a preludes harness and use it?

If so:
-Would we still have to do the DPFI to MPFI
-What plugs would stay/have to be swapped

Never done the DX base, any help would be sweet. (I have done research but couldn't find "solid" answers for my questions, if you can point me toward an answer or just fill me in, that'd be great)

 

No you cant use a Prelude wiring harness without extensive modification. Youre gonna have to do a multipoint conversion and even then it will render the rywire harness useless as its setup to work with an si chassis harness, unless you take the time to swap all the chassis wiring around to mock an si
