The only other thing that may have gotten damaged is the T-LP relay, but that it integrated into the internals of the body ECU, so to replace it you would have to replace the entire under dash fuse panel assembly.

I will check again, however, I have one of those fuse checkers with the illumination lights; the light on the fuse checker would turn on if the fuse is working ok, and it did that. Hopefully it isn't the T-LP relay; that would suck

Also, if you haven't done so already, disconnect that red wire from the OEM wiring to make sure that it is not just a case where something failed within the switch, preventing the T-LP relay from activating.
