Fuse box which ultizes the following circuits:
ECM power
starting
ignition
charging
emissions
MAF
MAF burnoff
Fuel puimp
fuel pump switch/oil pressure switch
Instead of these things running on a limited amount of circuits, I spread the load out thus if one thing causes a fuse to pop, it wont take out everything else with it, Problems can be narrowed down to one thing. (As opposed to having the ECM/IGN fuse under the dash pop, and not being able to figure outwhat caused it)
