3. Always install the sensor so that the tip the part in the exhaust stream is lower than the body the part where the wires exit The mounting position should be chosen such that the sensor will never become submerged Tighten the sensor to 45 N m 33 Ibf ft Over tightening or cross threading during installation will cause irreparable damage to the sensor if the sensor does not thread in easily and smoothly DO NOT FORCE IT check the threads as they may need to be cleaned or re tapped The black sensor harness should be routed away from sources of extreme heat and fastened securely to prevent damage Note DO NOT run the engine with an unpowered sensor in the exhaust stream This will cause premature sensor failure 1 5 RPM Input KWB4001 only The wideband controller is designed to work with most analog Tachometer signals Alternate sources such as coil triggers can be used if no tachometer signal is available DO NOT use signals from crank or cam sensors Connect the green wire included with the controller kit to the TACH source Note This wire only needs to be connected if you are using the FJO datalogging and analysis software and want to log the engine RPM MN 4001 rev C 1 6 FJO Digital Data Bus The FJO Digital Data Bus is a high speed digital port that allows up to 8 units to be connected and data logged using the software included with the KWB4001 kits 1 7 Status LED This LED shows the status of the controller
