LED Light Bars - Relays?

Perfect, I've done this on a truck a long time ago, but memory is foggy. Think I have found several online, but another diagram would be great.

LED Light Bars - Relays?

Does the ground need to be 12 ga. too or would 16 work for that? I know the heavier wire is needed for the power draw, but wasn't sure on ground.

Your ground needs to be as big, if not bigger.

Also - SPST relays are easy to wire, and not expensive. Go ahead and use them when installing new accessories. Don’t forget to add a fuse, to protect your new accessory and vehicle.
