what are these things?
Still learning a bunch about this bus but can’t figure out a couple of things. Yesterday was first time pulling a trailer and I just found out there’s a huge switch in my engine electronic compartment that changes how the 7 pin wiring works. I didn’t have brake lights and my trailer brakes were locked up everytime i hit the brakes until I just flipped this switch and tested then all the wires operated normally (still need to figure out brake controller) So what does this switch do and why would anyone want a 7pin wired any differently than defaults?
I also noticed on the side of the bay I can start the engine (which is SWEET) but what does RR start do?
Lastly in my drivers door there’s this alt 1/2 switch and T.T.LT ALT thingy. What does this do? My DN50 house alternator somehow was converted from 24V to 12V previously so I added a Wakespeed controller and is working great just wanting to make sure this thing doesn’t affect anything or if something I should be aware of.

RR stands for rear. Flip the 3 position switch up and you can start it from the rear. There is a start button next to that 3 position switch. The middle position is off and nither the front ignition keyed switch or the rear start button will work. Flip the switch down to the normal position and now it with start at the keyed dash ignition switch only.

Thank you! I saw the start button and tried it and it worked, I must of had the rr start flipped when messing with it. Still trying to figure out why a 7 pin trailer would need a different pinout and what the other thing is for
