Drats, the back of the gauges did have a small box maybe 1 inch by 1/2 inch, stupid thing did not have any studs though but was instead wired into the sheet of ( what do you call it ) .......that electrical tape stuff with all the circuits running through it.

I will have to look into this further, thanks
