How many wires on this are on correct pins from the 1989 Civic DX to the SiR. I know there will be extra wires to run for the Vtec knock sensor ETC. When I converted my DX engine harness for MPFI on my ZC I pulled today I bypassed those connectors so they are unmollested. My SiR engine Harness is complete and unmolested. The plugs are compatible, but clearly the drivers side one has a few extra wires, the passenger side on both are full. Anyone see diagrams comparing these connectors. as far as signals go. Obviosly this is a B16A1 engine. My old Converted harness was damaged pulling the engine, so repinning the SiR engine harness and adding extra wires on the DX side of the harness will be far easier than fixing the old harness.

The HAS to be someone who knows.
