As bad as I hate to agree with Bob the PD4045 is a very good unit and mased providing protected circuits easy.
I wired the wire outputs to a terminal strip and made a wiring diagram to keep track ot what goes where.
With the PD4045 you can pretty easily provide separate circuits to each major units and minor ones as well so that a problem with one won't kill more stuff.
My result shown below does not have the final lead dress, but you get the idea.
I also ran a separate ground from the ground buss on the new steel wheel well to each consumer since the ground return is just as likely to have a problem as the + lead
