Black box on fuel rail, What is it?
The other day I got towed
, was dropping cylinders, error code for 4,5,6, bank harness and injector number 4. So today I finally got it in the garage, fired up and ran normal 
, so just looking for the "simple fixes" like a poor connection or some thing. No such luck so far but I did find a "black box" that is between the fuel rail pressure sensor and the factory harness. Box is 2 inches long 1 inch wide and 1 inch thick.
Any clue what it could be?
Truck was purchased used, but I've own it for 2 years or so, not sure why I never noticed it before, everything else appears to be stock.
Any help or ideas would be appreciated, thanks
