Ive almost completed my wire tuck as well as battery relocation, ive also decided to remove my passenger airbag and tuck the large engine bay fuse box in that space and tucked the smaller engine bay fuse box inside of the fender.i am assuming the smaller fuse box powers the starter and the larger fuse box powers the alternator.and now im trying to figure out if there is a way to run one power wire from the smaller fuse box to carry power to both starter and alternator without having to run a power wire out of the larger fuse box now located under my passenger airbag cover on the dash.im currently using 0gauge wire from the trunk where the battery is now located to a distribution block where ive used 4gauge wire to connect to the large fuse box under the airbag cover.ive used another 4gauge wire from the distribution block to the smaller fuse box in the fender and intended on running a 4gauge wire from the smaller fuse box to the alternator and then jumping the connection from the alternator to the starter.any help or information would be well appreciated thank you
