Does anyone know what the different colors of a 3 wire instrument circuit? I have a reqmnt to use Black, Lt Blue, Brown. Which is the (+), (-)/rtn, and the Signal?

Best to get the manufacturer's literature and look it up!
Good on ya,

Did you stick the manufacturer and model number in Google? It often is quite a bit helpful to do so...

Light blue = battery positive
Brown = battery negative
Black = signal
Caused a good bit of head scratching when they showed up here in the USA.
Hope that helps,
