Need Help with gauge install Ok i am installing a air/fuel and trans temp electrical gauges. Well the air/fuel will be no problem, but when i got the trans temp it says i need to sources of power and 2 grounds...im guessing one is for the sender and one is for the lights. But i guess my question is does both of them have to be on a ignition switch or just one? Thinking about tapping into the headlight switch for one but dont know which one it is...found everything else i need through searches except this.
