Yesterday I had the bike out for a little ride and then did a full fluid change. Warmed the bike up, checked the levels. Started it and rode to the store. When I came out the bike wouldn't start. When I hit run the fuel pump comes on and then when I hit start the front headlight goes out, no starter noise at all, and I hear the fuel pump working again. Afterwards a red light is on on the speedo. I did the diagnostics and it said B2121 Starter Output Open/BCM Malfunction. I cleared it but still have the issue. I dug around and found this wire/connector right in the area of the starter/trans fill plug. I can't figure out where it plugs in. Any help is appreciated.
