All Wire Plus systems are available in configurations that support all stock and aftermarket Twin Cam ignition modules. There are some important factors to consider when selecting the proper wiring system for your Twin Cam model: Year of motor: 1999 motors feature a cam position sensor not used in mid 00-01 models (Sensor Configuration) Original Equipment or aftermarket ignition module: aftermarket ignition modules do not support the data link to connect to factory diagnostic equipment. Aftermarket ignition modules flash codes through the service engine light wiring provided in both Wire Plus systems Bank angle sensor: must be used on stock (and early model aftermarket) ignition modules Provides all sensor connections required by Original Equipment and aftermarket ignition modules. Includes connections for M.A.P. sensor, crank sensor, bank angle sensor, ignition coil and data link.
