The L67 swap Harness kit includes both harnesses required to place an L67 engine into a vehicle originally equipped with an L36 engine. The two included harnesses are:

• Boost Bypass Valve Harness (Plugs directly into PCM)
• GT to GTP Manifold Absolute Pressure (MAP) Adapter
  

Don't I also need injector adapters? Yes. Certain year vehicles require adapters to use the Bosch style connector found on the L67 engine.
