This Plug-n-Play Harness is used to connect an LS1 or LS2 MAP harness to an LS3 MAP sensor without having to cut and splice into your factory harness.
This Plug-n-Play adapter is commonly used on Chevrolet Corvette + Camaro, Pontiac Firebird + GTO & various Australian Holdens when converting your LS1 or LS2 vehicle to an LS3 MAP sensor.
This MAP adapter harness will fit other vehicles. Please view the detailed pictures to be sure this is the correct adapter for your application. In some rare cases the LS1 side of this harness may require the guide key to be removed as it is in the wrong position. This can be done with a razor blade or Dremel tool. The harness will still properly lock in place as it should.
