DEF / NOX Sensor Plugs.
These keep the CAN-BUS alive to the fuel tank and maintain normal ECU operation for fuel tank and lift pump data.
For 2017, 2018, 2019 GM 6.6L Duramax L5P
L5P Plugs will replace the nox and def module when the exhaust/def is removed from the L5P for racing. These keep the CAN-BUS alive to the fuel tank and maintain normal ECU operation for fuel tank and lift pump data. These plugs can be utilized so that the factory modules do not have to be left plugged into the harness and zip tied up.
