Installing the MC3 System
Installing the Junction Box
The junction box takes power from the vehicle and distributes it to the MC3 radio, GoBook,
and an optional EkaNet radio (when installed).
Before you can install the MC3 system for the first time, the junction box must be installed
on either the sled or a pedestal mount.
Once installed, the junction box should remain attached to the sled or pedestal.
To install the junction box
1. Remove the junction box from the MC3 kit.
2. Locate the sled or pedestal mount on which the junction box will be installed. In the
following example, a sled is used.
3. Using a Phillips screwdriver, remove the two screws holding the junction box bracket
in place.
4. Slide one end of the junction box into position over the bracket that is still attached;
be sure to orient the junction box according to the label on the sled or pedestal. The
junction box has a recessed edge that the bracket fits into.
