I have a 1977 LH OD and 4-synchro box installed in my 66B, so I don't have a
TCSA or gearshift-mounted switch. I installed a dash switch left of the
steering wheel in an existing hole. But I thought that switch on the gearbox
was a 4th gear contact switch. If not, what keeps the OD from being
selectable in 1st & 2nd?
