The Bendix
®
TABS-6
™
module pigtail uses a TTMA RP 97-
99 five (5)-pin Delphi 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).
Wheel Speed Sensor Connectors
Two (2)-pin connectors are provided for additional wheel
speed sensors for 4S ABS applications. These connectors
are labeled Additional Sensor Left (SAL), and Additional
Sensor Right (SAR). Extension cables are available in
various lengths from Bendix.
ABS Modulator Connectors
On Premium Bendix TABS-6 module pigtail harnesses, one
or two modulator connectors are provided for trailers using
two or three modulators. These three (3)-pin connectors
are labeled MOD2 and MOD3. (Note: MOD1 designates
the internal modulator of the Bendix TABS-6 module).
Remote modulator harnesses are available in many lengths
to satisfy most installation requirements.
