Ground question

Dumb question ahead: RaceCapture Pro Mk3, currently the ground wire is solely going to the SensorX breakout board which has the oil temp/pressure and water temp sensors connected- do I need to add in a separate chassis ground to the box or does it ground through the sensors?

Where do you get the 12v power from?

If you are using the OBDII cable, you shouldn't need an additional ground wire. If you are NOT using the OBDII cable, you must add a ground wire to your setup.

Thank you, I'm not using OBDII so I will add a ground wire. Power comes from my fuse block.
