[CA] AXIOM 12 with AIRMAR B164

[rarambarri]

Hello all,

I am getting an AXIOM 12 (E70369-00-LNC) to replace a 2008 E120. I've already figured more or less the NMEA backbone with STNG Starter Kit T70134. I'm also adding an ECI-100 to integrate my twin Yamahas into the display. And I plan to use the current thru-hull transducer Airmar B164-20.

So this is my parts list so far:
E70227 ECI-100 Engine Interface
E70242 Ray-Yamaha Command Link Cable
T70134 STNG Starter Kit
A80529 E120 to AXIOM 12 Adaptor Plate

I need an adaptor cable for Airmar B164 to 25 Pin transducer input on the AXIOM

So....

Q1 How do I connect Axiom 12 to Airmar B164-20?
Q2 Do I disconnect Airmar B164-20 from the sounder it is attached to and go directly to AXIOM?


Q3 What adapter Cable do I need?
Q4 And finally, Should I add a fuse to the backbone power cable (A06049) or it is not necessary?

Thanks for your time

P.S. I'm also adding a very unprofessional Diagram
