The xc has a low fuel warning light that comes on when the bulb in the tank gets uncovered. The sx still has the fuel bulb in the tank, but not the wirering from the fuel pump. I ordered the light and looking at the wireing diagram if I run a wire from the bulb wire to one side of the light, and tie into the orange wire for the other side the light will turn on when the fuel level is low. Beats running out of fuel in the middle of a hill. My question is what brand of moisture pack electrical connections matches ktm???
