2. Excess cable can be stored neatly coiled near the TCU, usually under the driver’s seat.
Installing the EDU Cable
The EDU Cable connects the EDU to the TCU.
Cable Run
Run Direction - In most vehicles, the EDU is mounted on the dashboard. The cable is routed from the
front of the vehicle toward the back to the TCU (usually mounted behind the driver’s seat). Leave the
coiled end of the EDU Cable at the front and route the uncoiled end to the TCU.
Routing Location - Route the EDU Cable internally.
Cable Dressing - For strain relief, the base of the coil should be secured with tie-wraps. The strain-
relief tie-wrap is normally positioned at the point where the cable transitions from a straight cable to a
coiled cable.
1. If possible, route the EDU Cable with other cables from the front of the vehicle toward the back
to the TCU. Be careful that you do not damage the connectors when pulling them through holes
or under carpeting.
2. Provide strain relief to the cable.
3. Plug the EDU connector into the appropriate slot of the TCU.
4. Plug the EDU connector into the appropriate socket of the EDU.
Installing the Handset Cable
The Handset Cable connects the TCU to the vehicle’s voice communication device.
Cable Run
Run Direction - The Handset is mounted on the dashboard. The cable is routed from the front of the
vehicle toward the back to the TCU (usually mounted behind the driver’s seat). Leave the coiled end of
the Handset Cable at the front and route the uncoiled end to the TCU.
Routing Location - Route the Handset Cable internally.
Cable Dressing - For strain relief, the base of the coil should be secured with tie-wraps. The strain-
relief tie-wrap is normally positioned at the point where the cable transitions from a straight cable to a
coiled cable.
1. If possible, route the Handset Cable with other cables from the front of the vehicle toward the
back to the TCU. Be careful that you do not damage the connectors when pulling them through
holes or under carpeting.
2. Provide strain relief to the cable.
