Nice! Did you get the bed light piece figured out? I'm not sure what settings would need to be changed for that if necessary. I'm still not really up to speed with AlfaOBD yet. I've just been following along with existing procedures for the changes that I have made so far. I don't have bed lights currently either so I am unable to verify.
I still haven't been able to figure out why some trucks have this enabled from the dealer and some don't. I'm sure it is related to something, but I haven't been able to connect the dots. I've discussed with quite a few, and some bighorns, laramies, limiteds, etc. come with it enabled while many of our trucks did not.
