NMEA noob needs help

I have a Garmin Echomap 93SV and I want to add the Garmin steady cast heading sensor. I ordered the sensor but now I need to setup a basic NMEA network.

I've found various NMEA 2000 starter kits, most have Two T connectors, two backbone cables, one power cable and two termination plugs.

The steady cast heading sensor does come with a T connector.

I need to hook up both the Garmin chart plotter and the heading sensor. The steady cast heading sensor has a built in NMEA ready cable.

Can this setup be done without purchasing any additional cables or connectors? If not, what else do I all need?

Thanks!

To make it work, my theory looks like this:

Termination plug - T fitting - T fitting - cable - T fitting - Termination plug

First T leg would get the power cable, second T leg would get a cable to my Garmin unit, third T leg would get the cable from my heading sensor.

Hope that makes sense.

You need a back bone kit.

Shop around for a back bone. The great thing about NMEA is that you can mix and match manufacturers components.

I have a Lowrance backbone (best deal) connecting a Lowrance paddle wheel (best deal), a Garmin fuel flow ( best features) Garmin GPS antenna (came with chartotter) and two Garmin chartplotters.

I actually ordered the Lowarance NMEA starter kit and based on everything I've read/seen so far, I should have everything I need to set this up.

Thanks for the link. I looked it over and it looks like my proposed setup should work perfect.
