Ok so I just attempted to attach obd1 ecu plugs in my 91 dx civic so I can run my p28 (i have a sohc vtec motor). Now at the end of it I had some extra wires and realized that apparently I accidentally connected the wrong wires to the wrong pins for a few things. Please look at my post here https://honda-tech.com/zerothread?id=1068809. So I can go and fix these obvious mistakes that I made, but that leaves me with the wires that were already connected to those pins, what the hell do I do with those??? What do I do now, to figure out where those wires go?? Is there somewhere I can find a list of all the wires that go from my stock DX harness to the ecu and what color they are?

Go on google and search for (your ecu) pin out. It will tell you the colour of the wire, what its for and its location in the original plug.
