OK, been working on a drag car for some time now. The chassis is a 85 CRX HF and was carbed. Motor is an OBD1 b16a from a 92 Integra XSi. So I basically started from scratch on the wiring. I bought a complete wiring harness on eBay for a 93 Integra LS. Had everything from fuse box to the tail light bulbs still attached. Following the factory service manual, I stripped all non-essential circuits from the harness. All I wanted it to do was run the engine. I went too far and removed the Service Connector wires. I do not have a dash either. I de-pinned all wires while doing this. I would like to hook up the Service Connector and MIL light so I can read trouble codes and I think this is needed to dyno tune unless I am mistaken.

I know the BROWN/WHITE (some cars it is BROWN) wire on the service connector goes to D4, but what does the GREEN/WHITE wire go to? D22? Ground?

Manual says it goes to the ECU. But where?
