6. MOUNTING CONFIGURATIONS
Tank (Nipple) Mount
The TABS‑6 Advanced module can be tank‑mounted using
a schedule 80 (heavy gauge steel) 3/4” NPT nipple directly
between the trailer supply tank and the module’s supply
port. A tank with a reinforced port must be used.
Frame (Chassis) Mount
The TABS‑6 Advanced module provides through‑holes for
frame mounting directly to the trailer frame rail or cross‑
member. It is recommended to use two Grade 5
3
/
8
‑16 bolts,
typical length 5”, torqued to 180-220 in-lbs.
7. PIGTAIL WIRING HARNESSES
Several pigtail wire harnesses are available to connect
the TABS‑6 Advanced module with ABS and other trailer
system components. Pigtail harness are weather sealed
at the connector interface and are clearly labeled for
proper installation. Because of the over‑molded design of
the TABS‑6 Advanced module wiring harnesses, Bendix
recommends that the complete harness be replaced if
damage or corrosion occurs.
TABS‑6 Advanced modules include the two primary wheel
speed sensor connections and therefore these are separate
from the pigtail harness.
ECU Connectors
TABS-6 Advanced module ECU connectors use an 18-pin
Deutsch DT series connector for brake light power, constant
power, ground, the trailer‑mounted ABS indicator lamp and
auxiliary I/O’s.
Power/ABS Indicator Lamp Connector
The TABS‑6 Advanced module pigtail uses a TTMA
RP 7‑99 5‑pin Packard Weather Pack connector for brake
light power, constant power, ground and the trailer‑mounted
ABS indicator lamp.
The Power/ABS indicator lamp lead of the pigtail harness
is available in several lengths to satisfy most installation
requirements (e.g. slider axles).
SAE J1939 (CAN) Connector
See Figure 6.
TABS‑6 Advanced module pigtail harnesses provide a 4‑pin
connection 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 module pigtails provide an option for up
to four auxiliary I/Os and two active sensor inputs.
Examples of uses of the auxiliary connector are:
• Lift axle sensing.
• Rear axle suspension air bag dump.
• Automatic lift axle control.
• External spring deflection sensor for mechanical spring
suspensions.
POWER AND GROUND
Trailer electrical power is supplied to the TABS‑6 Adv
module from the ignition and brake light circuits.
