What to I need to unhook to unbond the generator neutral from the trailer ground?

You will need a 1/2" socket (IIRC) to remove the nut on the back side of the genset frame gnd. lug. Pull off the L0 wire, be sure to reinstall the nut back on gnd lug, and then insulate the end of L0 wire with a few wraps of electrical tape. If you don't know where LO is located take a look at my post #3 in the other thread you started regarding grounding: https://www.steelsoldiers.com/showthread.php?172522-Mep002-proper-grounding

The sticky I referred you to, in post #3, has the LO wire identified in one of the photo's if you're not sure which wire it is.
