Factory GPS Plug

[OzTec]

Got a 2015 AR210 with N9K com code and speedo error. The Speedo keeps cycling back and forth non stop. No codes on YDS if plugged in to the harness in the engine compartment and YDS doesn't work if plugged in under the dash. There is no GPS antenna installed on this boat. Found the 3 pin plug hanging under the dash. no cap on it nothing. Is there supposed to be a cap on with a resistor plugged in? Cant find a wiring diagram/ service book for this boat ether. Parts diagram doesn't show anything for gps antenna.

traced the issue down to the port ECU being bad. changed the ecus around and the issue fallowed over.

At least you found the issue.

I noticed a few open plugs behind the helm too. I'm going to use one hopefully to power my chartplotter, but all others will be plugged just in case.
