C80 classic to EV100 wheel to T122 to Link 8

Welcome to the Raymarine Forum mzorn,

Q1. I'm guessing I can use a A06048 Seatalk NG to Seatalk2 Adapter Cable to go from the autopilot SeatalkNG backbone to the Seatalk2 port on the C80 MFD.
A1. It is not possible to do as you have suggested. A SeaTalkng backbone will need to be constructed to support interfacing the Evolution autopilot ACU, Control Head, and EV-1 Sensor Core. An E22158 SeaTalk to SeaTalkng Converter Kit will need to be purchased and installed as component within the backbone. The SeaTalk bus which presently includes the C80 and Raystar 125 GPS Sensor will need to be unplugged from the MFD's SeaTalk socket, disconnected from its present power source, connected to a D244 SeaTalk Junction Block, and then the SeaTalk Adapter Cable supplied with the SeaTalk to SeaTalkng Converter Kit will be used to interface the SeaTalk (yellow) socket of the SeaTalk to SeaTalkng Converter to the D244 SeaTalk Junction Block. Finally, a SeaTalk cable of sufficient length to mate the MFD's SeaTalk socket to the D244 SeaTalk Junction block will be obtained. This cable will be cut and then its yellow and shield leads will be spliced back together. This Cable's red leads will not be used and should be insulated to prevent shorting.

Q2. I'm also hoping to use a A06045 SeaTalk NG to NMEA 2000 Female Adapter Cable to go from the autopilot SeatalkNG backbone to the Lowrance Link8 VHF/DSC/AIS.
A2. Should the Lowrance Link8 VHF/DSC/AIS feature a DeviceNet Micro-C male socket or cable having a male socket, then the A06045 SeaTalk NG to NMEA 2000 Female Adapter Cable may be used for this purpose should you only desire to supply the Lowrance Link8 VHF/DSC/AIS with GPS data. However, As the software of the C-Series Classic MFDs was not designed to process NMEA 2000 PGNs containing AIS data, you may want to instead consider interfacing these products to one another via their respected NMEA 0183 communications interfaces.

Q3. And lastly, using a R08004 NMEA Input Output Pigtail Cable to go from
the C80 to the T122, part of the T104 Wireless Speed, Depth and Wind NMEA System. If the R08004 cable is correct, which color wire goes to each wire terminal on the T122.
A3. Depending upon whether you intend to use the MFD's AIS features (see the response to Q2) and whether you desire to have the Tacktick system using any data (ex. GPS) from the MFD, you may need to install a programmable NMEA 0183 multiplexer (ex. Actisense NDC-4) between the MFD and the NMEA 0183 talkers to multiplex the data from the Tacktick with the AIS data before sending the combined signal to the MFD's NMEA 0183 input port (white and green leads of the R08004 NMEA Cable).

Q4. Do I need to change settings in the C80?
A4. Should the MFD's AIS features be used, then it's NMEA 0183 port would need to be configured to "AIS 38400"
