SVS 4wd light comes on when it’s wet - 4x4 stops working

[OR_Eco3460]

This is my first post. I have an 2015 with 77k miles, rolling on an Icon 2” leveling lift and 295/70r18 KO3’s. Every fall when the rains hit, I am getting a subs 4wd light. My code reader is too basic to pick up a drivetrain code I guess. I’ve replaced the actuator twice (including $400 on what was supposed to be an OEM part - Mopar branded parts are not available). I have packed the actuator plug with dielectric grease so I know it’s not the actuator. Today it happened when I wasn’t even driving! I was hosing the mud off my wheels and fender wells before taking the truck for new tires and when I got in, the Svs 4wd light was on. This happens every time it rains… any help on tracing the location of potential water intrusion would be appreciated. I’ve heard there’s some type of junction box in on the firewall but that doesn’t make sense for where I was spraying water today. Is there a junction lower on the system that could be the source?

Not sure if it fits your problem but have you checked this connector that runs along the frame on the drivers side? It is known to work its way loose.
