Bob, it is in your electrical bay, which is where most of the chassis part of your 12 volt system is centered. That's the bay door frontmost street side, under the driver and in front of the wheel. The HWH module is upside down on the bay ceiling. The adjuster is on the module side facing coach front and toward the wall side, and a little hard to access. Follow the directions you downloaded.
I don't have the option to downsize these photos to fit in one post (1mb limit) using my current device, so find a second image in the next post.
