Wiring Dual DC to DC & MPPT Controller

Iol voltage drop does not accrue pmsl...
...as far as voltage drop. I'd presume you would use the same length and size negative conductor as positive so it won't make any difference because the resistance of the 2 conductors would be the same...
I'm sure Mr Ohm would have an opinion on the matter if he was around, lucky for us he left his law, just in case this situation arose.
On the other hand, Mr Dunning and Mr Kruger would be very impressed. Top marks :thumbsup:

Maybe you’ll have better luck than me but when I tried to explain this, complete with handy link to 12voltplanet very explicitly explaining it, it didn’t seem to sink in very far…
 
So just to get this right, sorry (I'm very new to this). Red wire from the vehicle battery to the Charger/Mppt (via fuse close to battery). Black wire from Charger/Mppt to ground (Rear seatbelt hole). Is that all ok? I have also been to run an ignition live to the charger/Mppt, can anyone suggest where to pick that up from?

Much discussion on ignition live sources. There's a section in the mainfuse box under the gear stick that contains a whole section that is ignition controlled. There are spare un-populated spaces in the fuse box. You can buy the connectors (ask @Pauly) that fit into the spare ways, to provide a dedicated ignition live feed. There are other options, have a read through this lot.
