LT1 to LT4 TMAP Adapter & IAT Breakout Harness

APPLICATION: This plug and play harness is required for adding an LT4 supercharger to standard LT1 engine harnesses.

NOTES: This harness converts the LT1 3-wire MAP sensor to the LT4 4-wire MAP sensor, and breaks out the IAT (intake air temp) from the MAF sensor for the supercharger.

It can be used on both standalone PSI swap harnesses and factory GM vehicles, including 2014+ Corvettes, 2014+ Vortec trucks, and 2016+ Camaros.

For factory vehicle applications, you will also need part # HAR-1101 to extend the EVAP connector.
