GTRA Brake Lights and what's this switch for?

A friend of mine just bought a GTRA and I was helping him get it ready for his first HPDE. One thing I noticed was there is no break lights. There is a rain light and the bulbs are dual element but for the life of me I can't find and brake light switch (pressure or other.) did the GTRA cars not have brake lights?

also on the right side edge of the center switches there is a 3 way switch with no label. it seems to be a switch for the instructor in the passenger seat. any idea what that is used for?

thanks for the help

The brake light sender should be inboard, follow the right rear brake line.

What year and chassis # is your friend's RA? Still running the 302 or other?

If I remember correctly it is Chassie number 3, all stock with 302, PI dash, Panoz seats, etc. looks like it may have some chassie updates. I thought I traced all the brake lines and never found a inline switch. I will have to look again.
thanks Chris
