Our LS swap harnesses also require the removal of the VATS and emissions systems from the PCM. This harness also requires the use of a Blue and Green P59 PCM service numbers will vary, which can be purchased from BP Automotive.
This harness is for pre-emissions vehicles or for off-road use only. This harness does not have provisions for EGR, AIR, EVAP, or Rear O2 Sensors. We can add these for an additional cost, however, in most cases, they are not needed. IF EMISSIONS ARE NEEDED YOUR HARNESS WILL INCUR A LEAD TIME.
