Can I use a dx harness on a gsr cx hatch? I purchased a 96 dx harness with everything you need to plug it into a gsr. It seems like it is missfiring but it is getting spark to all cylinders. So I am wondering if its because I used a dx harness for my cx hatch.

 

Why didn't you buy and EX harness? You also need to add wiring for the IAB and knock sensor since your car did not have vtec.
