Loud click with V10 ignition key "on"

[WB2020ClassA]

Anyone with the Ford V10 engine have the starter relay go bad? Last time I started my 2020 WB engine before winterizing I heard a loud mechanical sounding click. It stopped as soon as I turned off the engine and then started again when I restarted the engine. It sounds like it is coming from the rear, not the front of the engine. I am preparing for travel this year, and decided to check the engine again. As soon as I turn the ignition key to "on" the loud click started again. I doubt it's the starter solenoid because I did not turn the key to "start" and a bad solenoid will usually only click once if it clicks at all. I can pull the relay and try to troubleshoot it, but thought I would ask if anyone has had a similar issue with the loud clicking that sounds like it's coming from the rear of the engine with the key in the "on" position.

After more troubleshooting, it sounds like the clicking noise is coming from inside the dash behind the center console. It's not any of the relays.
