The reason that they supply the fuse cable is to put the BT module on a separate circuit, so if something happened it will blow its own fuse and everything else will still work.
All things considered, and this being such a great DIY write up, it's not hard at all to get those panels off once you know what tot do. Two hours max for the hole install. On the second car we did everything went so smoothly

If a separate fused feed is thought best practice then some power could be borrowed from the lights for example.
I've already taken about half the interior panels out that were removed in the (excellent) guide above and would rather not have to bother again!!
