Need Help with gauge install
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 two 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. Just got me confused on 2 different powers. The air/fuel only needs one.

I just saw on one of my searches where someone else did that.
What car are you working on 99corvette or the fbody in your sig? If you tie into a circut that runs through the BCM and your gauge shorts out you will pop your BCM. But hey its your ride.
Alright i gottcha. But if it is ran to the fuse panel..wont it pop the fuse first??
I am working on a 2002 Camaro. Will it hurt to run all 3 power wires to the same spot in the fuse box or will that overload it?
And one more thing. I heard of people getting there power from the cig. lighter, but mine works all the time not just when the switch is on...

[QUOTE=99corvette;12792845] Yes on the power side of the circuit. But if you tie into an existing ground circuit there is no fuse to pop.What I m getting at is it is better to run a new ground circut. Tie them both into one new ground.
I would run the both lights on one key hot power source then run the gauge on another.
You need to use a key hot circuit.
