Brake Shift Interlock, DRL Relay Coil,
Speed Control Module, Backup Lamps,
Trailer Tow Backup Lamp Relay Coil,
Electronic Shift On The Fly Hub Lock
Solenoid, Vacuum Pump Motor
If you have 4x4, I'd check to see if it's working. Water in an electric vacume pump can cause shorts. You might also try pulling Relay 38 under the hood, to isolate it from the circuit.
