I have a cobalt series wideband a/f gauge and I'm trying to find out why it doesn't have a back light... I thought all cobalt gauges lit up. It has 3 wires on the back and the hole isn't big enough for a bulb housing... Anyone know???

post pics please. I just put in all cobalt gagues in my car, there should be a white wire that hooks up to your headlight switch.
