The only way to be completely sure of which wire you need to connect to is to use a circuit tester, like part # PTW2993. Check to see if the light green wire or the red wire goes hot when you press the brake pedal. You want to use whichever of these two wires goes hot, only when the brake pedal is pressed. I believe on your van, it may be the light green, but use a circuit tester to be sure before completing the wiring.
