Located driver side installed to the frame…..had a random wire hanging from it and can't find where the other side plugged into.

"That component in your photo is the EVAP (Evaporative Emissions) Canister Vent Valve Solenoid on your 2018 Chevrolet Silverado.
Here's what it does and why it's there:
Purpose: It's part of the EVAP system, which captures fuel vapors from the gas tank and routes them to the engine to be burned, reducing emissions.
Location: Mounted near the fuel tank, typically on or near the frame rail above the rear axle.
Common Issues: These solenoids can get clogged with dust or debris, especially on trucks that see dirt roads or off-road use. When that happens, it may trigger a Check Engine Light with codes such as P0446, P0449, or P0455 (vent performance or circuit issues).
Maintenance Tip: GM released updated versions of this part with improved dust protection. Some owners add a small filter or relocate kit to keep it cleaner."
