PAI Industries aftermarket electric tachometer sensor in the Mack 64MT348M / 20706327 form factor. The bell-housing-mounted sensor uses a 3-pin rectangular connector and an 11.9 in . lead to feed engine speed to the dash tachometer and ECM across the 1997-2011 Mack range, including E7, E-Tech, and ASET applications. A failed unit typically produces a dropped or erratic tachometer signal, MIL, or speed-input fault code.
