If i swap an obd1 LS motor into my obd1 civic do i need the integra wiring harness and ecu or will the stock dx wiring harness and ecu work? i am not adding vtec so i don't need the vtec wire but what other differences are threre? thanks a lot.

The dx harness and ecu will work, the map sensor plug is on your firewall and wil have to be moved to the ls map. It would be better to run a LSecu, but the DX one will work.
