Wiring and Tuning
So you've got your junkyard LS or Vortec engine 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 a custom length harness and make it as simple as a 3-wire hookup. We can also flash your ECM/PCM so it will start up without unnecessary codes and security.
PCMs and Reprogramming
1996-2013 PCM reprogramming (LT1, LS series, or Vortec.) VATS/Security disable, standalone settings, dual fan enable, AFM delete, tire and gear change/speedo recalibration, etc | $100 |
| 2017+ Gen 5 ecm reprogramming | $175 |
| PCM (1996-2007) | $80 |
| PCM (2008-2013) | $100 |
Standalone Conversion on your stock harness and PCM
Vortec, LT1, LSx Gen 3, 4 and 5. Contact us for other GM engine platforms
All conversions include a PDM (Power Distribution Module), loom cleaned/replaced, non-essential components stripped out and are simplified to a 3-wire hookup. Includes OBDII port and available signal wires (Tachometer, speed signal, check engine, etc)
Gen 3 and 4 harness (99-13) standalone conversion | $375 |
| Gen 5 harness (2014+) standalone conversion | $450 |
| PCM base tune (security delete, tire/gear recalibration, standalone settings) (2017-2018 LT modules add $60 to unlock) | $100 |
| Dual fan upgrade (relays, fuses and wiring built-in.) (Gen 5 fan options unavailable. They use a PWM fan signal) | $75 |
| Convert drive-by-wire harness to drive-by-cable (Required TPS and IAC plug added. 01-02 PCM required for drive by cable to work) | $50 |
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.
Drive-by-cable, Manual Trans, Power Distribution Module, All new connectors, seals, and TXL wiring. Custom length trunk. Plug and play. | $750 |
