It's the factory ground. I don't work around wire enough to be able to tell the size by looking at it. It may be #8. Regardless, it is an accessory load. I plan to only run my new audio system (Radio and two amplifiers) off the aux battery.^Has to be as big as the + wire.
Or no worky and you fry stuff.
10ga off of any automotive size battery is merely an accessory load.
10ga for a ground is just silly.
I got my replacement relay from Rockauto. It is a hefty part. However, I couldnt install it due to coming down with a head cold. Also,, We're dealing with some weather issues here in Florida.
