As I understand yes, one wires will pull .003 amps or less with alt hooked up, key off, measuring from battery negative to positive cable off battery. And that is for a good one.

I agree going forward I only get 12si's or better with 3 wires controlled with ignition switch.

I will try the relay and let you know just for grins.
