deflection. The connection to the Electronic Control
Unit (ECU) is via the auxiliary 12-pin connector. see
Figure 6.
6. MOUNTING
Frame (Chassis) Mount
The Bendix ® TABS‑6 ™ Adv MC module provides three
M10, 1.18 in. (30 mm.) studs for frame mounting directly
to a trailer cross‑member. The TABS‑6 Adv MC module
uses three Class 8 steel M10x1.5 nuts with lock washers,
torqued to 354±44.4 in.-lbs (40±5 Nm). A bracket may be
used if direct mounting to a cross‑member is not possible.
7. PIGTAIL WIRING HARNESSES
Several pigtail wire harnesses are available to connect
the TABS‑6 Adv MC module with other trailer system
components. see Figure 6. Pigtail harnesses are weather‑
sealed at the connector interface and are clearly labeled for
proper installation. Because of the over‑molded design of
the wiring harnesses, Bendix recommends that if damage
or corrosion occurs, the complete harness be replaced.
Wheel Speed Connectors
The TABS‑6 Adv MC module includes two primary and
two secondary wheel speed sensor connections separate
from the main vehicle pigtail harnesses, and each requires
a separate harness.
ECU Connectors
The TABS-6 Adv MC module ECU has two connectors (in
addition to the wheel speed sensor connectors mentioned
above). The primary connector is a 7‑pin custom series
screw‑on type connector used to connect to the vehicle’s
power pigtail harness. The other connector is a 12-pin
Deutsch DT series style connector, used for auxiliary inputs
and outputs (I/Os).
POWER AND GROUND
Trailer electrical power is supplied to the TABS‑6 Adv MC
module from the ignition and brake light circuits.
see Charts 1 and 2 for output values and pin locations.

Power/ABS Indicator Lamp Connector
The TABS‑6 Adv MC module pigtail uses a TTMA RP 97‑99
5‑pin Packard Weather Pack connector for brake light
power, constant power, ground and the trailer‑mounted
ABS indicator lamp.
SAE J1939 (CAN) Connector
see Figure 6.
TABS-6 Adv MC module 12-pin auxiliary harnesses
typically include a 4-pin connector used for various ECU
communications. Typical uses include J1939 diagnostics,
and connection to the Bendix ® Trailer Information Module.
Auxiliary I/O Connector
The TABS-6 Adv MC module 12-pin auxiliary harness
provides an option for up to three auxiliary I/Os.
Examples of uses of the auxiliary connector are:
• Lift axle sensing.
• Rear axle suspension air bag dump.
• SAE J1939 Diagnostics.
• Automatic lift axle control.
• External spring deflection sensor for mechanical spring
suspensions.
