• Pigtail Wiring Harness: A power pigtail harness is
required.Auxiliaryharnessesareavailable,asneeded.
See Figure 6.
• Lift Axle Sensing: Ifatrailerisequippedwithaliftaxle,
thenliftaxlesensingmustbeused,unlesscongured
for automatic lift axle control (see below). A pressure
threshold switch must be installed in the lift bag for the
liftaxleandconnectedtotheECU.TheECUcanthen
monitor the position of the lift axle and will compensate
correctly for the load transfer to the other axle(s) when
the lift axle is raised.
• Lift Axle Control: The Bendix
®
TABS‑6
™
Adv MC can
be congured to automatically raise (and lower) lift
axle(s)whenapre-conguredloadissensed.
• Load Sensor: Ifatrailerisequippedwithanexternal
electrical spring deection sensor, See Figure 3, a
linkage is attached to an axle (but must not be installed
onaliftaxle)—within5(ve)inchesofthecenterof
the axle — connects to a load sensor attached to the
chassis of the vehicle. The output from the sensor is
an electrical signal that is proportional to the spring
