What gauge wire to run?
I think 18-20 ga. wire might be ok but that's just a wilda** guess.
Anyone here have a better informed suggestion?
It should fit the crimp connectors for the 4-pin white nylon connector and carry the 'load' easily.

And, what rating fuse? Recommendation is to run off constant power so makes sense to me to fuse it. I already have a good tap at the battery so won't be using an existing fuse panel.

I have the preassembled MPGuino from opengauge.org with the 3 vertical buttons and white 4-pin connector.
