What do I need for my k-planes and drive indicators to read to the nmea 2000 gateway so it can display my engine data on the chartplotter. I have everything else except for the trim and drive position. I want to rip out all the cables and mechanical gauges. I have looked but can not find anything and I am under a time constraint, want to splash my boat on Friday.

Thank you in advance for the help.

Livorsi has what you need not cheap though.
