Key Fob Functions

[Hypoxia]

I installed a new TriMark entry grab bar with the keypad and doorbell.  The original keypad had some of the lighting burned out and metal corrosion along with the acrylic handle crazing.  I also bought a new key fob which had to be programmed.  The fob has 4 buttons; lock, unlock, panic and a "gear".  I never knew what the gear did until today.  It activates  the salesman switch relay, a useless function for me.  The owner manual states it locks & unlocks the bay doors which I would like, I'll have to see if that is a simple change.

I also found a 7.5 amp fuse in the passenger arm rest.  I have no idea what it is for.
