Wiring Diagram
The diagram below shows typical wiring for a complete EVMS installation. It may look a little intimidating at first but should become clear as you start to wire up your own EV. Note that the diagram
does not show an inertia switch (crash sensor), which should be installed between the 12V battery and the EVMS Core’s 12V supply. You will also usually need to use the key signal to switch a relay for
powering auxiliary devices such as brake vacuum pump, power steering pump, water cooling pump, cabin heater, etc. Make sure all wiring has appropriate current and insulation ratings, and that fuses
have appropriate DC voltage and current ratings.
