(ET) F-N-R cam

[Neil Dennis <wombat RealNS com>]

I looked at an extra ass'y I had, didn't see an obvious registration
mark.  The wheel has to be engaged so none of the micro switches are
activated when in N position, just be careful that it isn't 180 degrees
out, the side with the 3 "bumps" should engage the switches in seauence
when moving up the F slot.
BTW, check the micro-switches while they are available, they do get
sticky after time and cause jumpy "shifting"
