I NEED HELP WITH AN INSTALLATIONâ€¦

I bought a 2001 sailboat with the following electronics already installed:

ST60+ Tridata connected via ST to a

ST-60 Wind Machine connected via ST to a

ST-6001 Smart Pilot connected to an Autohelm Model 300course computer.

There is also on board aâ€¦. Sitex Class B AIS transceiver connected to a Sitex GPS. (the transceiver has a male NEMA 2000 connector on the chasis.)

Standard VHF radio,

The ST-6001 smart pilot head works, but the screen is damaged so I purchased a new P70 autopilot control head to replace it. This unfortunately, I discovered , is not a plug and play situation. The P70 has the newer seatalk ng connectors on the back while the ST6001 has the old flat three prong ones. What do I do about that? How do I hook it up to the model 300 course computer?

The biggest part of this system is a new es128 MFDâ€¦ I would like to be able to hook up all my existing instrumentation to it.

How do I connect all these different things together? Please, someone give me detailed instructions. A diagram would be very helpful. If things are incompatible with sea talk (maybe the old autopilot computer) is there a way to hook them into the system using NMEA 0183?) Iâ€™ve received a lot of conflicting advise from the dealer and others who say they know what theyâ€™re talking about. Some say that the P70 will not work with the old computer because it cannot be calibrated...calibrate what? Can I leave the old head in the ST line to accommodate calibration?

Also, the autopilot computer and the MFD both require a direct 12VDC suppiyâ€¦ can there be more than one source of voltage in a Seatalk system (between Seatalk and Seatalk ng)? I would like to put the MFD on a separatecircuit breaker from the autopilot, but if a system has multiple sources ofpower can either actually be shut off?
