Quick question. I’m setting up an electronic oil pressure and oil temp gauges, just wondering where a good ground would be...

also would I be able to connect both grounds to the same point?

Thanks!

 

You can ground it pretty much anywhere that is metal. If it's painted, best practice is to remove a bit of paint to make sure it's properly grounded.

You can ground multiple things to the same point. If you look around the car when removing things, you'll notice quite a few factory ground locations with 6-7 wires.
