Sailing off wind angle - tack tick with ES7

[Aloha_float]

I have an EV100 autohelm with a Raymarine ES7 chart plotter and a wireless Raymarine tack tick system. I want to get the tack tick to communicate with the P70 controller so I can have the option of sailing off wind angle rather than heading only. Does anyone here know how to make this work with the Seatalk system?

There is an interface box for TackTick to Seatalk. Part number might end in 113. Looked at installing one on my last boat but never pulled the trigger.

I have the T104 system with the T122 wireless interface so I have the components to connect. I was told by a rep at last years annapolis show that it is simply connecting a wire from the interface to the EV100 main controller however, I don’t know what connections to use.

Did not mean to post twice however you can see the EV100 controller here which is mounted port side and the T122 controller is mounted starboard side.
