what up everyone. i just bought a new Tenzo tach gauge. first of all i want to know if the tach comes with a wire for the bulb or if it even comes with a light. theres three wires one red (+) black ground and green for the rpm's. i cant seem to find a wire for the light. the box says it has luminous number but what does that really mean. does the #'s light up or does the entire thing light up. in the side of the box the type of guage is PN# T-PTACH5-k i dont know if that help but if anyone out there has the same tach please tell me if it come with a light. thats
