High Amperage Ground location

[AH64ID]

Does anyone know what size this ground is?

I ran my 2ga winch wire to it, but want to make sure the OEM side is at least 2ga as well.

The stud isn't very large, but the cable coming off the drivers side battery seems to be.

Appears to be 1/0.

Appears to be 1/0.

That was my thought as well on the battery end, but the end in the fender appears a little smaller. Following the wire it looks like it splits above the frame with one end going to the block and the other to that stud.

My other option is to run it to the block, and use the bolt that secures the upper radiator hose bracket.

I don't think I have quite enough cable to make it to the negative battery terminal. I am using WARN's quick disconnect cable.

Isn't the 1/0 from the battery going to that stud ?. 1/0 is good for 125 amps. Connect there ?.

I used the bolt on the block that has the driverside ground wire on it.
Just in front of the ECM.
For my winch.

The block is the perfect spot for the winches ground wire as ot is the main ground from both batterys and from the Alternator itself that has a good job to do while winching.
Way better then just connecting it to one negative battery pole.
