Yeah, most of that Raymarine stuff from before they needed "course computers" and the electronics are all in the head unit, are interchangeable.

Yes, The only problem might be Seatalk connections, most Autohelm used "old Seatalk" round plug, Raymarine probably uses rectangular "new Seatalk" plug. There used to be an adapter available but round plug hasn't been used since the early 90's.

Or you could cut off the plug and fit mini crimp connectors to the wire. It will fit the mini spade pin on the st4000+ head. That's what I did when I did wiring work on the raymarine instruments.
