I have a 2021 212 where the GPS antenna is not working. The dealer shipped me a new one, but it's not reading, either. It worked briefly when we first got the boat, which leads me to believe it's a wiring short in the harness somewhere. Problem is, I can figure out where the harness terminates. The GPS antenna is a 3 wire plug that connects to a plug with a black, orange, and red/pink wire in the main harness. Both of the colored wires say "GPS" on them. Super! However, I cannot figure out where they terminate. The Connext screen plug doesn't have wires labeled as such, and neither does the module in the locker behind the helm chair. The 2021 workshop manual isn't published yet, but maybe someone with an older model has one with wiring diagrams? I can take it to the dealer, but then it's in for who-knows-how-long for something that is effectively non-essential for how we use the boat.

Anyone have the wiring schematic for a similar boat?

Any luck ever getting wire diagram? I need one for my 2021 212SE in particular the connect screen
 
Well, I did order and receive one of the factory service manuals. However, it still shows the older Connext screen with the separate analog tachs and not the single integrated screen model. Thus, it wasn't helpful for my GPS issue because, in the old design, the GPS antenna runs to the tach. I have been in communication with the Yamaha service folks who publish the book and they are working on an addendum.
That said, let me know what component you're looking for and I'll scan in the images that might work. Most of the book is engine mechanical.
 
I’m trying to figure out which harness and wires are for the audio. Amp input, speakers, etc. I’m trying to wire in the Wetsounds 10” Sub enclosure.
 
Not sure if this will be helpful, but it's what's in the book.

Appreciate this! It does help!
 
Why isn't the dealer fixing this stuff?
 
It's at the dealer now. I bought it in Dallas and live near Austin, and the Austin dealer was backlogged. So, we decided to guess our speed and enjoy the boat while the lakes levels were good and weather was nice. GPS is cosmetic, as I see it. Glad we waited because it's been 2 weeks with no resolution yet.
