when deconstructing the vitara harness to the engine harness I pulled this wire out of the computer, terminal C2-19 (C2 is the larger of the two plugs). I have been through wiring diagrams and plugged everything into the engine, I still cant find where it goes. on the wiring diagrams C2-19 isn't used on the plug and there are no grey wires with a white tracer. I have the five wire AFM denso computer. Any ideas?
