Help with Rhox upgradable LED light kit wiring

[Dustin Mustangs]

I have this kit (lgt-306e8l) installed and working but the lights and accessories have power even with the cart key in the off position. Is this how they are supposed to work? Is there a way to wire this so the lights and accessories can only operate with the cart key in the on position??

I also have the high low beam harness (lgt-169) which is listed as an accessory for this light kit but it did not come with any instructions and I can't find anything about it in the instructions that came with the light kit. How is this hooked up? I see labeled wires mentioning low beams by where the front light plugs into the main harness and also in the part of the harness that is behind the dash. And is the push button switch for this typically dash mounted or floor mounted for foot operation??

Finally, I also got a battery level meter... do I have to wire this straight to the batteries? And I assume it gets the full 48v?? What gauge wire is appropriate and does it need a fuse???

The cart is a 2013 Precedent 6 x 8v...

TIA!
