can i use a crx dx engine harness that has been converted to mpfi with an crx si body harness. I got a new 88 crx si body harness because my body harness was hacked up. I am having trouble finding an 88-89 si or hf engine harness, but I do have an 88 dx one that has been converted to mpfi.

 

Did they replace the shock tower connectors with the SI/HF ones?

 

If its on the body side of the fuse box then yes

 

you should be able too. a few pins may be different. my situation was a little different than yours, but sort of the same if that makes sense: i had si engine harness and a dx body harness. all plug n play EXCEPT my reverse lights never worked. upon further inspection, i had to swap 2 pins around on the dx body harness to match the si engine harness where the reverse switch wires go into the plug. i think youll be alright. can also verify by looking at the connectors and confirming the pins match on both sides(look at the engine side and compare to the body side, make sure the wire in matches the wire out) sorry if this all sounds confusing. just trying to help.
