You can do it at the fuseable link box fwd of the spare on the left front of the trunk, under the floor. The power cable from the battery runs directly from the battery to it, and can be taken off without taking the compressor assembly off.

I got home from a trip to find my new “click” style Gear Wrench torque wrench waiting for me. I have a digital, which although fine when working, always needs new batteries when I dig it out. Doesn’t matter if it’s been a week or a month between uses, they are dead. The new one was on a crazy sale so I grabbed it. 50 to 250 or 300 ft lbs. it also has a 15 degree one axis swivel head.
