Power Distribution Box Schematic?
 

Hi folks! I'm restomod'ing my father's 1981 F150 along the lines shown in my sig, and one of the many things I'm doing is to upgrade to a 3G and install a power distribution box. The box I've chosen is shown below, and others have ID'd it as having come from a 97/98 F150 with the aux trailer relay box. Can someone confirm that?

Also, I'm looking for is a schematic showing the box and associated wiring so I can get my head around how Ford used it. Does anyone have one they can show? I've created a generic one, shown below, but would like to see a real one.

Thanks!
