That's pretty sweet compared to the 4 pages for the kit I'm considering! The thing I like about this kit is the centralized location of all the relays you are going to need while allowing for plenty of future growth.
Kit looks complete other than battery cables.
I'm still waffling between them for a nice power distribution junction box with all the relays, Ron Francis for his well-known quality, and EZ Wiring for its quality at a very nice price point.
