I have a used NOS remote bottle opener. No instructions?
Unit has 3 wires any body know how to wire it?

Thanks Jay

One power (12V), one to ground, one to a switch.

Thanks for the quick reply, but I need to know the color coding.
Wires are red, white & black.
I think that it is wired like a Amp. Red 12V, Black ground &
white going to switch that is also 12V.
But guessing equals damage to unit. I was hoping to find someone that has wired one before to remove the guess factor.

You are right

Red is power
Black is ground and
White is for the switch
