2. Does anyone know what the red box arrowed in the second photo does
and/or what it contains? Do I need one or will it be alright to just run a
positive and negative wire from the battery to a female Powerpole connector
(if that's what it is) without that red box?
It's a diode pack to prevent the alternator (possibly) overcharging the
battery pack when the engine starts.

Brilliant, thanks Mike.
