Does anyone know what this extra ground wire is for? It comes from the main wire harness. Appears to be a ground but it’s not hooked up. Anyone else have this?
Yep. That's what it is. A factory sourced ground. Mainly used for the winch instead of hooking to the battery ground.
It's a effort to not choak down the elec system when winching.
Would/ could this ground wire be connected to a second battery or should it be grounded a different way? Also, when installing a stereo, how is the best way to ground it? Thank you for any advice.
