Usually there's one for ignition signal, one for dash lights, one for power and one for ground. Red is usually power, black is usually ground and you can probably figure out the other one by grounding black and trying the other two with +ve and see when the light comes on. If unsure use a 9V battery since it wont do any damage if you hook it up wrong (they can't supply much current). Hope this helps.
