Connecting 360 Imaging and Helix transducer cords?

[FryDog62]

I have the 7 prong transducer cable coming from the 360 Imaging transducer AND I have a 7 prong transducer cable coming from my Helix unit. I believe both are to plug into the back of the Helix but it only has one 7 prong transducer connection point.  

 

So I called Humminbird support a couple weeks ago and it was recommended to me to purchase a Mega 360 7-pin Transducer Y-Cable so it would all connect together - BUT I’m not seeing how it would work. I was envisioning more of a splitter that would allow both transducer cables to snap into the back of the Helix. 
 

Anyone figured this out before?

find your combo and it should list the connectors needed.

I have Mega 360 connected to by Solix up front along with the  transducer built into my Ultrex.   I used the cable they recommended.  It’s a y cable.  You connect one end to the fish finder and the other end of the y has two cables to connect to 360 and your regular transducer.   It’s very simple and there’s no way to mess it up that I can think of as long as you get the right y-cable.

I got a call from somebody from back home that wires boats and I think he got me figured out.  Hope so!!
