I have no idea what the position or range is... they were on my bike when I bought it, they've now been removed. I would think that SATO has this info posted w the product. I do know that the passenger portion can be added. Brake switch- the stock rr sets have a ? fitting that pulls a spring that operates a mechanical switch, the SATOs didn't have that provision when it was on my bike. I would think that is SATO dosen't have the hardware, something could be fabed up to pull/operate the switch. I hope this helps.
thanks for looking- J
ps- I'll send some pics tonight
