ARG 12V Bulkhead Harness Routing Diagram F48-1270 - Ford RV Chassis 19Z90020

This document is sheet 4 of 5 of Allied Recreation Group (ARG) drawing 19Z90020, revision B, titled "ELECTRICAL ROUTING BASIC." It is an isometric routing diagram of the 12V bulkhead harness for a Ford chassis (harness part number F48-1270), typical of a motorhome/RV build on a Ford cab-chassis. The drawing shows the physical routing of the harness across the front bulkhead structure, with numbered balloon callouts (2, 4, 6, 7, 8, 10, 12, 18, 22, 24, 28, 34, 40, 68, 72, 85) referencing clips, ties, and hardware, presumably itemized in a bill of materials on another sheet. Labeled connection points include the clearance lights harness, wiper relays, dash harness connection, bulkhead harness fuse relay box, side marker lights, headlight connections with harness F48-0374, the Ford O.E.M headlight connection, O.E.M horn connection, A/C compressor, miscellaneous harness connections, ground points, and a lead "to front overhead." The title block records drawing dates of 2014-06-16 through 2014-07-08, revision A (initial release, 2014-06-20) and revision B (added notes, 2014-07-08). A reader can learn where each front-end 12V harness branch routes and connects on the Ford chassis bulkhead, though no fuse values, wire colors, or pinouts are shown.
