Wiring on Communication Connector

[montanabay]

Hi All,

Setting up NMEA 2000 with my DF115 (year 2005). It has the 8pin connector from the ECU, 5 wires go to the connector, the colors are: black, gray, orange/yellow, black/green, and yellow.

So far I've figured out that:

Black = ground
gray = pwr/ign

but I'm sure on the others.

NMEA 2000 standard is:

Wire 1 = ground
Wire 2 = power
Wire 3 = data 1
Wire 4 = data 2
Wire 5 = insulator

Can anyone help help me figure out the which are data and which is the insulator?

Thanks!

Josh

If you already have a NMEA 2000 network system in boat then you would need
990C0-88034 Engine Interface Module
990C0-88008 NMEA 2000 Cable,25ft
that will connect engine to network.
