I did a 94 gsr swap into my 98 ek, everything was wired up it starts but it sounds like a harley davidson sounds way out of time. we used my stock dx harness and used plugs off of the gsr harness to make the 2 work. Its throwing 3 codes with a 98 gsr computer. I was recommended to use a 96-98 ex harness and get a obd2-obd1 jumper and a obd1 ecu. can anybody please hep me out

 

The rerason people suggest to use aa EX harness is because it will save you the trouble of running the 2 vtec wires. But besides that it's the same.

What are the codes?
