Ground Wire Gauge for Additional Wiring of ETBC7L

Question

Question:

Im installing a 7-Way RV Upgrade Kit Item # ETBC7L. I bought extra 12 gauge wire to route to the engine. I also need extra ground wire to the frame. What gauge is that? Also, I have a Subaru Outback 2020 and Im not sure where to attach to battery so I dont mess up any electronics. Any assistance would be appreciated. Thanks,

You'd want to use 10 gauge wire like part # 10-1-1 which we sell by the foot.

Attaching to the battery is a matter of going directly to the positive post of the battery and you'd be set.
