Speed sensor wire on class C?

I'm installing a new stereo with navigation into my 2018 Chateau (E450 chassis). The new stereo requires a vehicle speed input. Does anyone know the location and color of the wire that I can tap into for vehicle speed?

The vehicle speed is carried on the CAN data bus. There are adapters that convert the data signal into a speed signal your new GPS could use. Most adapters plug into the OBD II port to access the CAN.
