In designing power distribution for my base '07 H3 electrical mods, my first approach was to build a Blue Seas auxiliary fuse box with an 80a breaker. I'll be powering two sets of spots and floods off the front and a set of floods on the rear, and CB, so this feels like overkill. The H3 fuse box has empty spares along with empty slots for the sunroof motor and a couple of other accessories not included in the base model.

My questions is, is adding the auxiliary fuse box worth it (outside of having a cool post on the build thread)? The empty slots range from 20 to 30 amps, more than what I'll need - couldn't I just tap those?

 

you can plug in a fuse but you need to find the output side wire, if there is one?
adding one might require pulling the assm up. its been shown here but I don't remember where. you might search and find it.
might be ezer to do it your way!
