2.
Remove both endcaps from the extrusion.
3.
Slide all lenses and dividers out of the extrusion.
4.
If your lightbar has a protective
housing fastened to the extrusion
behind the power supply, trim this
housing as shown in Fig. 1.

11. Return the reflector to its mounting area in front of the
cable access hole and secure with the original screws.
12. Install the plastic (not metal), power supply mounting
brackets that are included in this kit (if your lightbar is not
already equipped with these brackets). Be sure that
these are positioned in the PierceAlert mounting area.
13. Locate the short stand-offs and the Internal-Tooth Lock
Washers included with this kit. Insert the lock washer
around the threaded shaft of the stand-off and screw the
stand off into the plastic power supply mounting bracket.
14. Slide the lens spacer (included) into the bottom lens
channel of the extrusion. Position this spacer directly in
front of the power supply.
15. Slide the cover seal (included) into the upper lens
channel of the extrusion. Position this seal directly in
front of the power supply.
16. Plug the PierceAlert into the two-conductor that was
installed earlier (either connected to the matrix board or
routed into the vehicle).
17. Return all lenses and dividers to their original locations.
18. Position the PierceAlert in it’s mounting area in the
extrusion. Insert the alignment tabs into both the upper
and lower lens channels. Be sure the lenses on either
end of the PierceAlert are behind the PierceAlert
housing.
19. Secure the PierceAlert to the stand-offs with the supplied
Phillips-head screws.
Do not tighten theses screws yet!
20. Install the endcaps on the extrusion and tighten all of the
endcap mounting screws.
21. Tighten the PierceAlert mounting screws firmly.

8.
Route this harness cable to the PierceAlert mounting
area.
9.
If there are no available option ports on the matrix board,
or if there is no matrix board present, route the two-
conductor harness cable up through the cable access
hole, into the extrusion and directly to the PierceAlert
mounting location.
10. Route this two-conductor cable along the same path as
the existing input cable for your lightbar, and connect it to
either an existing switch-head or to a user supplied
switch. Refer to the wiring diagram for details.
