you are correct, the dude who got banned is seats and such, he hooked me up on some all leather heated and vented front and rear seats, center console and the dash panel. The dude sells good stuff, on ebay, but is a little high strung. I was a ****** to this and between techauthority.com and my dealership, I added vented seats, that are not a factory option, added all the missing harness pieces by extracting them from a complete harness from a truck with all the options and added rear heated seats with the console buttons, My nav shows everything and I am very happy, but I think the reason the seats and such guy got banned, is he sells you the product and that's the end of the sale. I tried to get him to help me more, but that's not what he does, he supplies seats and when it came to contacting WIC to get the build list opened up and codes added to it that are not options, the BCU flashed, the new harnesses and buttons, it was all me. I am very happy with my purchase and the dude is a good guy, but he cannot dedicate weeks to training everyone of us and that is why I called him hi-strung, He sells seats, not upgrades your truck. TO end, any express can get upgraded to every option on a 4x4 Longhorn Laramie if you want to open your build list and replace your harnesses. its work, but its well worth it.
