I'm wiring up a multicade, and I have a thicker gauge wire sending the 12v to the coin door lamps directly from the PS, but I'm using the thinner ground wire from the JAMMA harness as the ground from the lamps. Is it okay to have them mismatched like this? Or do both the ground and power wires going to the lamps need to be the same gauge?
