Should have come back here long ago and left a review. The materials are top notch as well as the service after the sell. It has bene a while since I installed mine but for some reason one of the wires was just a bit too short. Got it replaced no problem. Everything working as it should as far as I can tell now.

This wire upgrade, new batteries and a new starter and my rig "explodes" to life when you hit the key.

I also should've come back with an update. I ordered my Big 3 kit for a 95 7.4, but held off for way too long before installing it. Ended up needing a new alternator, so I installed the kit while waiting for the Powermaster to arrive. No complaints, and everything fired up first try. Running cable along the passenger frame rail to the starter was awkward, but not too bad. The gauge in the cab actually reads roughly what it should, for the first time since I've owned the truck, but that's probably a combination of the cabling and double the alternator output.
Definitely recommend it, and if I bought another of these trucks, I'd buy another kit.
