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.

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).

POWER AND GROUND
Trailer electrical power is supplied to the TABS‑6 Adv
module from the ignition and brake light circuits.
