ARG 19Z90020 12V Dash Harness Routing Diagram - Ford Chassis RV (F48-1758)
RV 12V dash harness routing drawing (F48-1758, Ford) showing power mirrors, radio memory, blower motor, A/C compressor, dash lights, 12V outlet and generator/aux start switch connections to Evans HVAC.
This is Sheet 3 of 5 of Allied Recreation Group (ARG) engineering drawing 19Z90020, Revision B, titled "Electrical Routing Basic," showing the 12V DASH HARNESS—FORD (part reference F48-1758) for an RV/motorhome built on a Ford chassis. The isometric drawing depicts the dash assembly with the harness routing and numbered attachment/routing points (items such as 4, 6, 8, 10, 12, 13, 16, 20, 24, 28, 30, 81). Callouts identify connection points for the power mirrors, ground buss bar, Evans HVAC (see Detail A), 12 volt outlet, radio and radio switch, radio memory instrument panel, generator start switch, aux start switch, driving light switch, lighter, leveler touch pad option, bulkhead harness, and chassis ground. A separate wire fan-out detail on the right labels leads for the blower motor, blower motor ground, A/C compressor, dash lights, and dash lights ground. The title block records the drawing history: initial release (Rev A) 2014-06-20 and Rev B "Added Notes" released 2014-07-08, drawn by 044kipfef, with tolerances in inches at 1:1 scale. A reader can learn where each dash-area 12V circuit connects and how the harness is routed across the Ford dash structure.
