Additional Info
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 Red and Blue PCM service numbers 12200411 or 9354896, which can be purchased from BP Automotive. This application uses an Electronic Automatic Transmission applications which will also require a double pole brake switch for converter lock-up control. This can also be purchased from BP Automotive by selecting yes in the drop-down when purchasing your harness.
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. Please email us if you wish to add emissions.
