Not your average "behind the dash clicking": 2011 Limited EL 4x4

I've had a clicking sound coming from behind the cluster panel area since I bought my rig about a year and a half ago and it hasn't gotten better or worse. It is definitely not an actuator or any macro-mechanical type sound for that matter. It's a ~4 per second gentle clicking that persists while the vehicle thinks someone is inside. If I trick it to think that I've parked and left the vehicle, it stops once all the accessories shut off. No idea if it continues while the engine is running because it's such a subtle noise. I have full functionality of all accessories, cluster components and HVAC so there's not a smoking gun pointing me in any direction nor is there a parasitic draw large enough to effect battery charge. It just makes a little noise that you might not even notice if there's any quantity of background noise.

I want to guess that it's a relay wigging out but I have no idea what that actually sounds like. But, if I had to guess what that sounds like, this would be the noise. It's such a quiet tapping that even if I try to record the sound, my phone doesn't catch it. I've done my due diligence to collect symptoms and all I have to go off of is high frequency clicking from behind the cluster, power is on the same circuit as the accessories, no notable parasitic draw, no known presence of faulty or degraded system functionality. Anyone have ideas/ways to diagnose this one?

I've never dealt with any exploratory electrical system issues before so take it easy on me and just picture the confused John Travolta scene from Pulp Fiction but holding a multimeter instead of his coat.

Did you ever figure this out?

Nope, still clicking away.

I’m not experiencing anything adverse electrical or otherwise but I just don’t like that it’s happening because idk if it’s doing something bad or hurting the rig somehow…

But a battery charger on the battery, turn the ignition on then start pulling one fuse at a time until the clicking stops. Then you know what circuit has a problem. Get a one vin subscription to your vehicle from alldata or similar and start tracing for suspects.
