Wiring and Tuning


So you've got your junkyard LS engine or Vortec 350 and now you need to get it running. The wiring harness and computer can be very intimidating. We can modify your used harness or build you another and make it as simple as a 3-wire hookup. We can also flash your computer so it will run at it's peak performance.

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 power module 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.


Drive-by-cable, Manual Trans, Power Distribution Module, All new connectors, seals, and TXL wiring. Custom length trunk. Plug and play.
