This harness adapts the LS harness from separate MAP and IAT sensors to a single TMAP sensor like the factory Hellcat sensors or the LT4 TMAP sensor.
 
Select either Gen 3 or Gen 4 to match your harness MAP connector to the adapter harness.
 
If using a Holley ECU, the LT4 TMAP sensor is preprogrammed in the ECU.
