Yep and then you can scroll through the speedo/tach/whatever. Back in the day before everyone had GPS and could use that to check vehicle speed, the secret gauge was a great way to set your needle back on after you did white faces. Keep the clear cover off the cluster temporarily, set the odo to speedo and set cruise on a straight stretch of highway. Then just stick the needle on and good.
