Vanagang:

I ran a 12 gauge wire under the drivers seat from the aux battery to the
fuse box area with the intent of connecting circuit #3 (interior lights,
radio, etc.) to the aux battery (with fuse #3 permanently removed from
the fuse box and a new 15 amp inline fuse installed--described as quite
an easy thing in the archives).

Right off, however, I can not see where to connect the new wire to the
#3 circuit at the fuse box.   Do I have to remove all of the relays and
fuses and open the fuse box further to continue? If so, do those of you
who are fuse box savvy have any cautions, insights, or tips besides
ground strap disconnections in advance of the work?

Thanks in advance.
