switch_panel_physical_3sw 2014 RAM 1500 Carputer β€” FULL PHYSICAL WIRING: 3-switch dash panel, DIRECT to the Waveshare over ONE Cat5 (every wire + connector shown) Each control point = a LIT momentary switch (4 pins: NO, COM, LED+, LED-) + a SEPARATE state-indicator LED (anode, cathode).  All conductors are 24 AWG Cat5 (mA-level). Every wire end into a screw terminal gets a FERRULE.  Rails fan out on small terminal blocks (WAGO 221 / DIN).  This is the 3-per-Cat5 budget, drawn physically.  Scale: repeat per Cat5, or switch to a panel Modbus module for 8/Cat5.
