Autohelm 5000 Drive to Garmin GPH 12 Autopilot

[mrfssd]

I am trying to help a friend to install a new Garmin Autopilot into his boat since his last autopilot die.

However the drive he have is from the old system and it is an autohelm 5000 drive unit..

Anyone know how to hook this thing up?

I know its a long time since you posted but in case you are still monitoring.
There is a post I made a month ago about my experience installing a Garmin GHP12 autopilot to replace a Robertson autopilot. I used the existing hydraulic actuator and pump but everything else was replaced including rudder position indicator.
