AiLi 12 volt Battery Monitor fitted in the Land Rover Discovery 1 Gull wing

Like most people iv had some spare time due to the Covid-19 an lockdown so iv finally got round to fitting the Battery Monitor to the gull wing.
I originally looked at the Victron version of this but after a bit of research found the AiLi, it does everything the more expensive Victron unit does but for a fraction of the price.
It comes with a shunt which is fitted on the negative side of the battery and a wire to the positive side as a reference.
Here is a link to the Amazon listing for this battery monitor, in it there is a wiring diagram of how this fits.
