No the needle and pin are not indexed or marked to fit in any special way. Since the needle has female end and the gauge has male end just slip the needle over the pin. There is a stopper pin under the number "0" on this gauge to stop the needle from going down further and actually you can sweep the needle all the way up with your finger and watch it fall all the way down to 0 by itself when the gauge is out and no power applied.
