I wasn't able to find my A/P photos last night, but if you look at the
Bensons1 photo (under Files on this site) you will see the cantilever
mount on the starboard side of the cockpit. It's the lighter, brass-
colored thing - the darker socket just to its left is the 4000+ ram's
electrical socket. The round electrical socket farther to the left is
for the 2000+ which I use as a backup. (I have three independent A/P
systems - it's Raymarine after all!)
For position, you want the ram to be close to level, 90 degrees to the
tiller and 18" from the axis of the rudder post.
One caution when using the cantilever bracket: Since the cockpit wall
isn't quite vertical, under compression the pin on the ram (or ST2000)
will pop up out of the hole. (This always happens in close proximity
to another boat while you are clearing a winch over-ride.) That's why
under the socket you see a flat piece of SS with a hole in it - it's
to tie the base end of the ram down.
