I was looking at the auxiliary battery for wiring in a 1500 watt sine wave inverter and noticed a few plugs not going anywhere, I know sometimes the loom is the same for all cars depending on the additional spec or not...

am I missing anything important or nothing to worry about with these plugs?

Also should I wire the inverter into the aux batt or the main batt? due to the power I'll be pulling I think ill need to have the engine running anyway (re-charing Rc batteries - big capacity ones quickly)
