Ecco Vantage 12+ Series Installation & Operation Instructions page 7

Permanent Mounting
1. Determine the location of the lightbar, and the best route for the wiring.
2. Determine the position of the mounting feet and drill the 5/16"-11/32" diameter mounting holes accordingly, if needed.
The spacing of the mounting feet from left to right is adjustable. It is suggested that the positioning of the feet be symmetrical and near
the curved edges of the roof where the roof is strongest. Ideally, the outermost holes on the feet should be used for installation. The inner
holes on the feet match the hole locations for ECCO 15 series lightbar and can be used when one of these lightbars has been
previously installed.
3. Mount the lightbar, with the bolts going through the holes drilled in step 2, routing the wire as planned in step 1 (refer to diagram). See
the Wiring section of this manual for further wiring instructions. Install washers and nuts and secure the unit.
