      As an automotive instructor that teaches students on all levels I think the best advice would be to draw out the circuit that you are thinking about introducing voltage to. Draw the probe in the circuit then trace out what the ground path would be ,What is the load, and is it normally subjected to 12V, 5V, or a signal. I would be especially careful if the ground is through an ECU.
