Which wires on the noids are the positive and negative? None of the noids including the purge has it marked on it. WTF! Do we just guess. It didn't come with any instructions but I found some on the net. However they didn't specify which wire is which. Help!

It shouldn't matter on noids, unless TNT noids are different from all others. Just ground one wire and run the power to the other one through the relay.

I've never used any other ones so I could say if they are different but there is no indication as to which is which.

Yep, they're just like a lightbulb ... give one side power, and ground the other side, and off they go.
