Hello Bowen,
The jedi warrior you mentioned is Lin. I'm sure he will chime in soon.
I've copied from my post, what he wrote.
By the way, since you are beginning to go to the dark side (albeit an enlightened dark side) --- I installed the Cape International Heater assembly that has an internal fan (2 speeds). I love it. I use the original heater blower to move fresh air into the passenger side of the interior. It gets colder in Virginia than in southern California! In a BJ8 you wouldn't see a thing behind the central console.
Bowen, have you tried contacting Cape International?
