Yamaha Genny EF3000iSEB Inverter Board (new in 2017)

A few weeks ago, I was camping with my teenage kids, and one of them turned on the Genny while it was plugged into the RV, and the Air Conditioner was still turned ON. Afterward, there was no A/C output, and the A/C green light never turned on. I bought a replacement inverter board, but it was missing a connector for a 12V, with large gauge wires. My guess is that was for the "boost" option. I am looking for the correct part number for it. I have attached a picture, showing the old one, and the one I ordered (which is missing a connector), which I had to send back. Thanks for anyone who can help me locate the correct part. I know they are $700 - $900. So, I hope this time around, I can get the correct one.. Thanks, all! Oops, still need to use the old method for attaching pictures? Jussec... The original board has a sticker on one of the large CAPS that reads, "7CH-DO (120V) 14010572"
