Hand-Drawn 120V 3-Way Switch & Light Box Wiring Diagram Sketch

This is a hand-drawn electrical wiring diagram sketched in ink, showing a household-style 120-volt lighting circuit rather than a vehicle-specific schematic. The drawing depicts a multi-way (three-way) switch arrangement: a 120V black hot feed runs from a box labeled 'Panel' up to a 'Switch Box,' with traveler conductors labeled Red and Blue (the Blue label corrects a crossed-out 'White'/'Black') running between the two switch boxes and up to a 'Light Box' containing a lamp fixture. A white wire is explicitly labeled 'White Wire (Neutral),' and wire nut splice points are called out in two locations ('Wire Nut'). On the right side of the page, two additional fixture/box symbols are drawn with 'Black' and 'White' conductor labels, apparently showing additional lights or receptacles fed from the same circuit. A reader can learn the intended conductor color coding (Black = hot/return, Red and Blue = travelers, White = neutral), where the splices (wire nuts) are made, and how power flows from the panel through the switch boxes to the light fixtures. Despite being filed with a 1979 Ford F-150 gallery, the diagram contains no automotive content, part numbers, fuse data, or vehicle references.
