    If I recall correctly, that is only a 1/4" bolt thread. Not as big as it looks on the head.

    I watched this video while in Tractor Supply gathering 10ga wire & connectors. I plan on installing right after I install my new fuel tank. Thanks for the info!!

    Just did mine with the Kascar kit, quick and easy.
    I also added an extra cable from the local shop between the heads, overkill...but it's done.
    Next project

    I've installed the kit on mine and I've had not a problem.

    I'm a DIY'er to a fault, so this was a rewarding project. Electrically speaking, the more wires in the cable, the better, which means it will feel heavy and very flexible, similar to a jumper cable. I picked up a length of 6-3 electrical cable 6' long, then stripped the shielding to yield all the wire I needed. The end product is a highly conductive system of 6 ga wire (approx .25" conductor dia), soldered all connections and fastened using star lock washers. Great preemptive fix. Thanks for the ideas and pics.

    I did this modification years ago and have never seen a lot of the problems mentioned here. I used a very flexible 8 gauge wire to build the harness. I wouldn't use solid wire as vibration will break it in time. One of the weakest points in the HMMWV body grounding is the ground behind the heater controls where it comes through the body. My solution was to take a piece of 1/4" all thread brass rod and bolt it firmly to the body using star washers to guarantee good electrical bonding and then all of my wires attach with a separate nut and star washer so the mounting nuts never get disturbed. And as mentioned in other posts, anti-oxidant grease helps keep things corrosion free. It's cheap insurance.

    Did the grounding kit install from Kascar. It took me about 2 hrs. Personally spent too much time walking back and forth in the shop getting the right sockets, so here is my contribution to this thread;

    It's those metric ones that really throw me. Any rhyme or reason to this? And thanks for that, could've used it about a year ago.

    Engines originally sourced from GM and they adapted to metric long ago. Military still prefers SAE for less tool and bolt proliferation.

    Most OE vehicle manufacturers have switched to metric.
