New, custom-made harnesses (4.8, 5.3, 6.0, LS1, LT1)
Great option if you are changing intakes and/or want to hide the PCM in the vehicle. Also keep in mind where you'd like the main fuse box to sit. When ordering a new harness provide info on how long you need the fuse block trunk to be from a given point on the engine as a reference. Also how long you need the harness-PCM trunk starting at the center rear of the engine block on top. Hand-made in the U.S.A.

Wiring and Tuning
