WABCO 2S/2M Installation Instructions Manual page 35

Appendix II
Ideally, cables should be affi xed to the rigid structure of the trailer. However, structure is not always
available on tank-mounted installations. In these cases, securing the cable may be accomplished by
fastening the cable to nearby air lines. It is important to note that cables should be secured only to the
extent that the cable is held suffi ciently in place. Refer to Figure 32 for 2S/2M-4S/3M ABS.

7.1.4 Sensor Extension Cables at the ECU
On valves that are tank mounted with no trailer structure nearby, or have remote-mounted cables, the
sensor extension cables are attached to the air lines. Cable clips are preferred over zip ties. It is important
to remember that cables should be fastened in a manner where the cable is secured enough where the
cable will not move or chafe against what it is mounted to. A small amount of slack should be present to
ensure that the cables do not become taut after installation or the servicing of components. Figure 33
illustrates the correct amount of slack in the sensor extension cables and correct attachment to the air
delivery lines for ABS ECUs.
