Hello,

i have 2000 civic intially d16 obd1, and now swapped d15b dual vtec (p2j-003 manual transmission). My harness has 2 pin DLC that when i short, i can flash the CEL and get the codes.

I want to add the 16 pin DLC, (I believe p2j-003 is Obd2), is it possible? If yes, someone can guide me about the wiring and pinouts for 16pin DLC to my existing to p2j.

note: my car doesnt have 16pin DLC already. It was obd1. But i have the 16pin DLC and would like to wire it to my ecu.
