Attention: TDR Forum Junkies 
On a 2002 3500 the spare mini fuse in the fuse panel in the side of the dash has one leg (the fuse leg closest to the floor of the truck) wired to the accessory bus.
Instead of cutting anything or adding anything, the Painless Wiring line to the Acc bus to activate the Painless relays, just put some solder on the pink wire to stiffen it and shape it to fit the fuse leg slot plug into the acc side of the spare mini fuse.
I did try to solder the wire to a leg I pulled out of a old mini fuse and the aluminum leg of the mini fuse melted before the solder flowed.
