Mounting the eHorn-HV
The eHorn-HV can be mounted on any relatively at surface with the supplied
mounting brackets. The mounting surface must be capable of supporting the
weight of the eHorn-HV. Four installer-supplied 1/4" screws are required. Use
screws that are suitable for the mounting surface.
For dimensions, see Figures 1 and 2.
To secure the eHorn-HV to the mounting surface:
1. Hold the eHorn-HV against the mounting surface and use the four mounting
holes on the bracket as a template. Scribe drill-position marks on the
mounting surface.
2. Remove the eHorn-HV and drill a hole at each mark.
3. Secure the eHorn-HV to the mounting surface using installer-supplied
1/4" screws.

is provided with 12” 14AWG wire leads with an Aptiv (Delphi) 2P male connector
(Aptiv p/n 12010973) for customer connection. Wire polarity is as follows: red +
(positive), black - (negative).
