New Style ATO Fuse Box conversion

[snipescastle2]

Hey Guy's, just wondering if anyone has even done a Late model ATO fuse box mod for their trucks? I'm looking into doing this, I know there are already companies making these (American Autowire, M&H electrical Fabricators, etc...) I found a website that someone has done this for their truck, I may try this, but wanted to inquire here first and see if anyone had any experience with the pinouts/terminals needed to be changed, before I set out to do this. I have an extra main harness, so I can work with that one while I "Iron Out" the details. I'd appreciate any insight into this before I dive into it head first
Thanks!
