I read the Smartgauge manual where it says to wire directly to the battery posts. My house battery bank consists of two 8D's which are only paralled together via the 1-2-ALL switch. All of the batteries' neg posts are wired together (incl. a separate eng start batt), but not the positives. What would be the easiest way to install the Smartgauge under this scenario, or would it require two?
Thanks for your time.
