    LT4 supercharger 4 wire TMAP sensor

    Installed a LT4 supercharger on an LT1. The LT4 supercharger has a 4 wire TMAP sensor in the rear location. The conversion harness connects between the MAF, extends to the LT1 3 wire MAP connector only, and then over to the 4 wire TMAP sensor on the supercharger. What do I select in the MAP Sensor Config to read the TMAP correctly?
