Line a baking sheet with foil and then place a grill rack over it.
Put your pork tenderloin on the grill rack and lightly season all sides of the pork tenderloin.
Using toothpicks to keep the bacon secure, wrap the entire pork tenderloin with bacon.
Smoke the pork tenderloin at 225 degrees for 30 minutes.
Adjust the temperature on your smoker up to 400 degrees.
Drizzle maple syrup over the pork tenderloin and continue cooking the bacon wrapped pork tenderloin until the internal temperature hits 145 degrees. (about 30 additional minutes)
Let the tenderloin rest for 15 minutes before slicing.

Notes
Use thin cut bacon for the wrap. I usually prefer thick sliced bacon but choosing thin here allows the bacon to crisp up better.
