Installation Guidelines for the TABS-6 4S/3M Side/Axle ABS Configuration:

o MOD1 (TABS-6 ABS Unit) controls the left “road-side” wheel(s) of a primary axle(s).

o MOD2 (Bendix® BR9235™ Modulator Unit) controls the right “curb-side” wheel(s) of a primary axle(s). o MOD3 (Bendix® BR9235™ Modulator Unit) controls the wheels of an additional axle(s).

o SL & SR (Primary Sensors) senses wheels on the primary axle (always on the ground) that MOD1 controls, and are connected to the dedicated 2-pin connector on the TABS-6 ECU.

o SAL & SAR (Additional Sensors) senses the wheels that MOD3 controls, and are connected to the 18-pin connector on the TABS-6 ECU.

o For lift axle applications, MOD3 controls the wheels for the lift-able axle
