E70153 and ST4000

Hello
Q:How to connect ST4000 and E70153 in order to use Windvane mode (Windtrim) on ST4000 to get Autohelm Sail to Wind Angle.

I’ve got my boat (Catalina 36, 1985) with ST4000 installed. ST4000 Control head is installed on port side of the boat at the end of the cockpit beside the steering wheel. By tracing the wires, I believe I have following setup - please see first two diagrams.

Couple years ago I have installed Raymarine kit (E70153) with I50/60 Sailpack Wind, Depth, and Speed System.
All i50 and i60 instruments are installed on the cabin wall facing cockpit. Transducers are connected directly to correspondent instruments. The power is provided by SeaTalkng Power Cable (A06049). - Please see attached diagrams for details.

I would greatly appreciate your help. Alex.
