I will check the power to the switch via the blue wire, if there is no power in the blue wire is there anything I can? I hope it is the switch, I have a new box of those switch from a past project I will try them. really don't want to drive 275 mile with no speedo. I will let you guy know what I find out about the power. the gauge acts like the blue wire is not connected internally. as i said hope it is the litle switch.
