    i have been looking everything over in my truck because i am planning a trip so while i was checking fuse's and such i had out the chilton just making sure the correct fuse is where they are supposed to be when i got to wondering what are the aux a and aux b hooked up to? the chilton doesn't even mention them any ideas? beacuse they are supposed to have 30 fuse's in them but aux b has a 20

    Aux A and Aux B are auxilary battery power hook-ups. On mine, Aux A feeds my e-lights, Aux B feeds the trailer brake.

    Look at your diagram - the posts above the fuses you circled are the corresponding outputs. (toward the firewall when you look in the truck) These give you a good solid connection for bigger power draw equipment.

    Hopes this helps,

    I just added some lights to my Suburban and used both of those Aux spots. Seems to be working fine - go nuts!
