Question:
We have a Spectro junction box on our dump trailer and are wondering if we can hook battery to junction box to maintain battery charge. And if so which terminals would we hook to?

The Spectro Junction Box part # 38656 can have a 12 volt accessory circuit added to it so that you could put a maintenance charge on your trailer battery but it does not have a specific pin to use for this circuit.
You would just need to pick an un-used pin in the box and run the circuit from the 7-way to it and then from it to the positive post of your battery.
