Power setup in cab

This isn’t what I set out to do but it’s a start. We are trying to put 7 blade flat Rv plugs on all our tractors for powering monitors, diesel pumps, invertor etc. In middle of wiring one I found a little USB / volt meter / 12 v plug for 20$ on Amazon. Tractor is old enough and rough enough I just cut a hole and popped it in. Handy dandy.



Edit used switch for the spreader monitors I’m trying to get setup.
