I have a 2007 Z21 Ranger with NMEA backbone, blue connectors (not the new RED) and LMS-332C. I have been talking with my dealer about the parts and pieces I need to install an I-Command Digital gauge to the network. They are telling me I need new cable, an integrator at the back of the boat, etc. I have seen on this forum that all I need is the engine cable to connect to the NMEA T connector and then connect the I-Command digital gauge to the NMEA network under the console. They are telling me about $500 for all the parts and pieces vs. about $45 for the engine cable and $250 or so for the gauge on this forum.

So, I-Command guru's what do I need to do to install an I-Command digital gauge to the EMM on my 2007 225 HO ETEC? I just want info from the engine and display GPS speed and RPM on the I-Command.

Confused!!
