Interfacing an A series MFD to a Yamaha Comm. Link

Hello,
I would like to interface a MFD to my twin F250GET motors.

I would like to make sure I have all items/part number needed for this interface before I place an order

1 ECL-100
1 T70134 Sea Talk Starter Kit
1 E70242 Raymarine Yamaha link cable (not sure about this one)

Is there anything else I may be missing??

Thanks
