Have an '05 42 Fountain with virgin 525s and zero issues. Was winterizing yesterday and saw a 2-wire connector from the wiring harness at the right rear of the starboard motor unplugged. I plugged it back together and then looked at the port motor and sure enough it was there and still plugged in. I haven't noticed anything wrong! Any idea what that connection is for? I tried to look online but I'll probably need the service manual to look it up.

Thanks guys!!

Picture of the plug? There are different connections for smartcraft functions.
