I just bought a new control pack for my 8274 which has the new style solenoids on it. It came w/ about a 14-16g ground wire that I grounded to the motor bolt.
The main ground cable goes from the rear motor through-bolt to the battery. I used 2-gauge on mine, had to make a new one that was long enough to reach. The (original?) cables that came with my 32-year-old 8274 were 4-gauge.
Years ago the 4 gauge that Warn puts on most of their winches melted through part of the plastic grill on my '80 Hilux 4X4 so I upgrade my cables to 2 gauge and pay closer attention to not overloading the winch.
Bigger is better when it comes to high amp applications like winch wiring. So long as you can make a secure attachment with the end lug to the winch, go for it if you can afford it.
Another thing to consider in grounding the winch is whether you're going to run two batteries on it. Consider that the ground will usually be longer than the power lead from the solenoid. The short power lead may be OK with both batteries running through it, but the longer ground may not be.
On my rig, I ran a double ground, so each battery has a lead from the winch. That neatly prevents the problem if your power cables from the solenoid are the same size as your grounds.
