Default Harley Gauge/Fuel Pump Error???? Please Help

The fuel pump (i think) sounds different this morning when i turn on the ignition. Neither the gauge fuel indicator or the stock fuel indicator is working now. It shows i'm empty but the tank is completely full. The red light is on as well on the gauge. I ran the diagnostic and it gives me error codes for the BCM that are all related to the signal lights. Probably because i switched over to LED lights weeks ago so i'm not really worried about those codes. But I also have the speedo error code b1210 which simply tells me to replace the part number 70900391. Thats the whole gauge though!! That cannot be correct. Please help!!!!

Here is a video
Right when i flip the switch, it sounds funny. Not like it did yesterday or any other day. It sounds weak or something. Hard to describe.

The weirdest part of all of this is my bike starts and runs just fine. Rode to work without a problem.

Instructions for that speedo says fuel gauge needs to be enabled. Maybe some sunspots or a subspace anomaly caused it to reset. Maybe try and enable it again?

Doing some reading on the error codes i had, i found a post saying they had lost the function of the rear driving light. The brake light worked, just not the driving light. That is when i realized i had too... so long story short, i found a wire that was causing my problem

I was in a rush because i was running late for work. When i put on my windshield, i pinched a wire and it was touching metal, causing a short.

Problem fixed
