Basically but the cluster may not be a full 12 volts. I would hook that dimmer up and check the voltage coming from the wires. If its 12 volts, the you should be good to go.
I had gauges like that in my mustang, and i didnt use the dimmer switch, I just hid it behind the gauge cluster. I never really dim my gauges anyways
^ya I dont either. I was thinkin about hookin it up and leaving the switch on full blast and just tucking it up behind the dash. thomas, is all I do is just take off the clear cover to my guages and pull the needles off then put that one on top? or do I remove my factory one?
