Relay Panels - Ground Trigger?

I think the main reasons for ground triggers in this auto world is stuff like DIY EFI. Such as Holley and others, the outputs for switching are all transistors to ground.. Just as these relays are set up

THERE IS HOWEVER some disadvantages to this. If something shorts, and the circuit is not well protected, you cannot kill the power..........with the switch. So if you are, say, running some relay coils off a common 10A circuit, and one relay coil shorts, you might make some smoke before the 10A fuse blows

There is "some" concern in racing, but obviously that has been ignored. If part of a harness shorts in a crash or other malfeasance, it might activate some relays you don't want activated....like the fuel pump.

One thing you MUST PAY ATTENTION to especially when using such as control modules, EFI, etc, is polarity with solid state switching, as well as polarity of the "spike" diodes. If the thing is wired reversed, the spike diodes can blowup your control circuits.
