Ok I put a 1997 Acura Integra LS Engine in my 1998 honda civic DX I used my stock DX wiring harness on the LS engine but when I plugged in my LS ECU(p75) It wont run good. but when I plug my DX ECU in it seems to work Alright. I went to the junkyard today to get an LS wiring harness but that will NOT WORK on the DX honda civic HB. They told me to get The Honda CivicEX wiring harness Will that work or will it be the same as the DX Wiring harness PLEASE HELP ME I NEED MY CAR Its been 3 weeks already
