Strain Relief at the ECU — Tank Mounting
It is necessary that cable connections to a component, such as an ECU valve assembly, display a visible
amount of slack in the cable up to the first tie or clip that secures the cable to the trailer structure or air line.
This first anchor point should be a minimum 6-inches (152 mm) of cable length from the cable/component
connection and a maximum of 12-inches (305 mm). This applies to all sensor, power, valve and GIO cables.
Regardless of whether zip ties or cable clips are used, cables should be secured at intervals not greater
than 18-inches (457 mm) to avoid cable vibration.
Ideally, cables should be affixed 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 sufficiently in place. Refer to figure for 2S/1M ABS.
