Recommended Power Wiring
Short circuits may result in severe electrical shock or burns.
Remove the appropriate vehicle fuse and test the circuit to ensure
that no power is present before connecting the power cable.
The switchplate requires an 11-16 VDC power input. A quick-
tripping circuit breaker or fuse should be installed between the
switchplate and vehicle power. Circuit overload protection
should be rated for 5 amperes. If vehicle power fluctuates widely

range DC/DC converter power supply should be installed. Test
the voltage and polarity before making connections to vehicle power.
