Re: 72 fuse box upgrade needed?
Just got back inside from doing some custom wiring....here are a few pics of the mods to the 56...
The bulkhead serves as the common BAT junction now where the leads from it are:
8ga to alt charge post
10ga to horn relay (which is also where the interior feed for the ammeter's from)
12ga lead to BAT +12V
12ga lead to ALT remote voltage sense
12ga lead to the dash mounted pushbutton start switch
coming soon will be a 12ga feed for the headlight relay upgrade and IGN relay too. The OE headlight/front lighting is trash so it's getting an upgrade. We're trying to keep most of the wiring basic but upgrading as we go-my father in law opted to NOT go with electric fans so this 78A SI charging system upgrade is plenty for this ole truck of his.
