Flanders cab dash panel relay connection diagram for autonomous drilling operations. Shows the wiring for several relays incl. the horn, ignition, engine starter, and light relays. I’ve included the OEM 12-way Deutsch plug pinout too. The schematic covers the engine stop relay loop which is normally a closed hardwired circuit. You get all the wire color codes (BLK, BLU, RED, YLW) and terminal block connections (12M01TB1). Standard A3 format. It’s for the Salobo autonomous drilling project by Vale. and double-check the pin-outs as they can vary between machines.
