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!
