I’m attempting to confirm that the autopilot RAM is in fact this model: Simrad HLD2000L MK2  

Screenshotted from this site near bottom of page: http://www.jgtech.com/shop15.htm

Irregardless for now I’m uploading the manual so I will have handy access as I continue the investigaton and definitive identification.
Simrad HLD2000L MK2 Manual

Relevant pages from the manual for electrical appear to be these two:

Seems I need to contact Simrad technical support to determine which wire is + and which is – for the “drive engage” i.e. clutch.  The power definitely connects to A / B and according to Raymarine is reversing polarity (which is why it is marked A / B and not +/-)

Called Simrad tech support 3-12-14 and they indicate clutch polarity is either way… Does not matter just needs to be energized is what they said. Seems we are almost ready to hook this up. Need cable for p70r head and determine it’s mounting location

Seems ferrite gets installed on flux gate cable
