One of the most critical aspects of the Columbia’s electrical design is the multiplexing system. Unlike older trucks that used individual wires for every single switch and bulb, multiplexing allows multiple signals to travel over a single pair of wires (the CAN bus). This reduces the physical weight of the wiring harness and minimizes the number of potential failure points. However, it also means that a single damaged wire can cause a "cascading failure," where multiple seemingly unrelated systems—like the windshield wipers and the turn signals—stop working simultaneously. Accurate schematics reduce diagnostic time from hours to
