04. After we initially cut the gauge holes of the bezel, we switched up the Dremel bits and then sanded the holes smoothly, taking time to check the hole size as we went along.
05. As you cut, constantly check the fitment of the gauges into the dash bezel holes as you trim and smooth the holes for the gauges. Ideally, you want the gauges to fit snuggly in the bezel, even without the backing cups. And you definitely don’t want to make the holes so big that the gauges fall through the bezel!
06. Depending on what size gauge you’re installing or what dash bezel you’re working with, you’ll need to trim, cut, and smooth until you’re satisfied with how the gauges fit. If the gauge’s fit in the bezel is very snug, you may be able to get away with not running the backing cup, but we put backing cups on all our gauges so they never vibrate out in off-road conditions.
07. Wiring up gauges is not difficult but it is time consuming, and doing a good job takes even longer. Auto Meter includes all the sensors and senders necessary with each gauge. Wiring for most gauges consists of a power wire, a ground, a sender wire, and the illumination wiring.
08. To add the Auto Meter gauges into your Chevy dash bezel, you’ll need to cut out and remove the factory instrument cluster and wiring behind the dash bezel. We suggest not trying to reuse any of the old wiring, and instead just get rid of it. You’re better off running all new wiring to each sender or sensor for your Auto Meter gauges.
