so I'm trying to wire up a custom video switcher for my car to do exactly what this does (only need video tho)
here's the diagram that @
MmmDieselFumes drew up a while back, but looking at it shouldn't +/- for each input be on the same relay and not 1 is all + and 1 is all -? just doesn't seem like it would work or it would try and activate half of each input this way
