switch live

So I'm in the process of fitting airride to me 2016 highline. I need a switch live. Id like to not interfere with the loom. Iv read lots about taking from the middle row of the fuse box with a piggy back fuse. The problem i am having is when I'm checking the fuses with a multi meter they show...

Gents help is required :( I purchased an inverter/LB and split charger for my T5 a few years ago and never got round to fit it o_O, anyway I've since purhased a T6 and have decided to fit it only to find it won't work.... After many night trolling the net I found that the new vans are fitted...
