I flat tow my 2017 Edge behind my motorhome.  I've got pin7 of the wiring harness connected to the battery to keep a trickle charge on it.  For my Brake Buddy I currently have a 12V plug I clamp to the battery and have an extension reaching inside to plug the Brake Buddy into.  I do this of course since none of the 12V plugs inside the Edge have continuous power.  I'd like to install a new plug (or even reroute the wire for the 12V plug on passenger side of console) to a continuous hot feed.  Which fuse in the interior fuse box can I grab for this?

I did use this switch - https://www.amazon.com/dp/B08CVNKPKY/ref=cm_sw_r_cp_apa_glc_fabc_AK70AE8CT00GWN4K5JPC

I ran a new cable from battery negative to the switch and then connected existing negative cable to the other side of the switch.  Works great.
