would it be alright to use the same ground and switched 12V source for all three of my gauges?? I was thinking about wiring them all together then just routing one wire to each source instead of three different ones.

I kinda figured that the gauges won't pull that many amps. What do you guys think??

 

The gauge wire don't matter, keep it up above 16.

 

I know this but I was wondering if I would use the same wire for all three gauges to ground them to one source and one power supply.

 

yes u can

 

Thank you!!
