Description

Our LS1 standalone harnesses are designed for installing these new GM EFI engines into your ride, whatever it may be. This swap harness is specific for 1997-2006  5.7 engines with RPO Code LS1 and LS6 with a Drive by Cable (Mechanical) Throttle Body and EV1 Injectors and a 4L60e Transmission.

On 2003 and newer applications leave a note with your PCM service number (if your PCM is DBC capable) so we can install green retainers on the harness.

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 which will also require a double pole (4 Terminals) brake switch for converter lock-up control. Some 1988 and later GM vehicles were equipped from the factory with this type of brake switch.  If your vehicle has a double pole brake switch you can use the one in the vehicle.

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.
