So you did the swap but you don't know what the wire is for? Trace that wire back to the ecu. Refer to this thread: https://hondaswap.com/reference-materials/ecu-pinouts-28667/ and it will tell you what pin on the ecu that wire is going to. I'm pretty positive you have an obd1 ecu, so refer to that list.
