They will 100% not output signal when using a manual transmission. We offer the PAC-2800BT fan controller with Gen 5 harnesses for this reason. ADDITIONAL ITEMS REQUIRED: E92 ECM, T43 TCM (6L80E), T87 TCM TCM (8L90E/10L90E) Your engine might have used a different ECM, our harness is designed to use the E92 ECM. A T87A is required for Gen 1 10 speeds (pre 2019) while a T93 is required for Gen 2 (2019+) 10 speeds. The harness will plug into either TCM as they use the same plugs, there are no differences on the harness, only within the computers and computer programming. * An OBD-II Speedometer / Tachometer (P/N STA-1000) is available from PSI to supply Tachometer, Speedometer and Check Engine LightTRANSMISSION COMPATIBILITY:6L80/90Es: Must be 2013+ model year transmissions to work with a Gen 5 LT system.8L80/90Es: 2014-2018 gen 1 model years currently compatible.
