I would ALWAYS mount it directly to the main battery ground cable.. Even if I have to splice another ground wire to it.
Same for the positive wire.
You will need everything the battery has from time to time.
My favorite is one of the batteries with both Chevy and Ford posts on it. I like to use the chevy ones for the vehicle and the Ford ones for the winch.
