[CA] Networking E120 classic with E120 Hybrid

[mcduck52]

I have added a E series classic MFD to the helm station and have a E series Widescreen HybridTouch under the cockpit dodger installed by the previous owner. I wish only to have basic information from the existing ng network (like GPS data) and have been led to believe it is possible by your reply to my original post. This will work for me as the helm station is to be used only for navigation in close quarters using a seperate chart card. What connectors do I need to get from the seatalk connector on the back of the classic to the existing ng backbone some 15' from the helm station? I can only find a short adapter cable to go fron seatalk2 to ng on the classic and then a 5M spur cable to rout to the backbone. How can I connect the two? Must they be spliced?
