After @airline tech saved my butt, Rusty started right up with no error codes and the blend box working perfect. The replacement was a full day job (mine was a bit messier due to a lot of added wiring), but was not difficult but was tedious. My recommendations are:
1. Get a small hex drive angle drill adaptor that makes the firewall box screws super easy. (I did them twice while figuring out how to get the box mounted) and it was painless.
2. I used a 3/8 air ratchet to remove the main dash bolts since they are tight all the way out. Saved a lot of time ratcheting.
3. The box is a super snug fit, more than I expected. Because it has 2 studs that stick out from the firewall, I started by setting it in place and putting in the top screws. This made it impossible to get the bottom set, even used a ratchet strap. It has a flange that goes all the way around that is very tight. I ended up removing the box, slightly bending the firewall studs upward, and screwing the bottom screws in. Then you can start tightening the nuts on the firewall studs while ensuring the flange around the box lines up. As it pulls forward you will be able to install the screws and clips ending with the top two on the firewall side.
4. Remove the front seats to give you room to move around.
5. As mentioned before, the allen bolt next to the windshield only needs to be loosened a few turns.
6. The worst part of the wiring disconnect/reconnect is around the fuse box. Take time to unplug and pull the wires/ plugs back behind the dash before pulling the dash. The video recommends pulling the fuse box which I didn't do but may make it easier.
7. If you have a cordless drill, get torx 20 and 25 hex bits which will speed up removal and replacement of lot of screws.
8. If you forget to shift out of park, once you remove the cover from the shifter you can push a small white tab under the bsck of the shifter that you can push to shift.
9. Be very careful making sure you confirm all wire plugs are reconnected, maybe make a list as you unplug. The one that caused me a problem which completely immobilized the truck was a small 2 wire plug that @airline tech tracked down. This is mounted to the inside of the center console near the dash. I didn't see it when removing the console and pulling the console back to remove it unplugged that connector, so i was not aware of it. This was the smallest plug of all and made a huge difference.
10. Use light gloves because everything is sharp, otherwise you will need a transfusion at the end of the project.
11. Use ziploc bags to keep hardware with each part. This made reassembly much easier and i had no left over hardware when i was done.
