My 04 only had one computer so I would assume yes. NNBS trucks have a PCM and TCM I believe, which is why most handhelds cannot turn off torque management on the NNBS's.

its on the drivers side, infront of the motor, kinda lined up with the edge of the radiator.

it has a little black cover, and will require a ratchet to under the plugs.
