P700 Chassis Ground

[Hondabits]

On my 2020 P700-4d, I’m installing a full size second battery under the drivers seat for winch /plow etc... I’ll charge the battery through a True Isolator, and run other accessories off a Buss connected by a Stinger Relay.
For the winch, I’m running 4gauge power cable directly to the winch relay.
I was looking to use the frame to run my grounds.
Anyone have a favorite ground point up front? Maybe the master cylinder mount bolts? A frame bolt? Any suggestions?
And then maybe the middle, do you ground to the engine. Or a frame bolt?
Or maybe I should just run a 4 gauge ground cable up to the winch as well?
I’m just wondering what worked for you?

How bout just anywhere clean on the frame! Thats what I did with all my chit and it been 6yrs no problems. Work smarter not harder and don't overthink it. 🤟

You should do this so the power loop will be isolated to only the second battery.
