Wiring the LED Message Board System in the Vehicle
3.
Secure the mounting brackets to the Message Board with the 1/4-inch hardware.
4.
Start one 8-32 thread-forming screw in each sliding bracket, in the end most easily
accessed.
Do not tighten the screws at this time.
5.
Mark the locations of the 3/8-inch mounting holes.
DRILLING PRECAUTIONS: When drilling holes, check the area you are drilling
into to ensure that you do not damage vehicle components while drilling. All
drilled holes should be deburred, and all sharp edges should be smoothed. All
wire routings going through drilled holes should be protected by a grommet or
convolute/split loom tubing.
6.
Drill the marked mounting holes with a 13/32-inch drill, and drill an appropriate cable
hole as needed.
7.
If the mounting surface is less than 1/8-inch thick, use the 9/16-inch flat washers
between the mounting brackets and surface. Loosely assemble both sides with the
3/8-inch hardware.
8.
Route the cable.
9.
Level the Message Board and tighten the nuts.
10.
Tighten the 8-32 thread-forming screws just enough to keep the Message Board from
sliding on the mounts.
Do not pierce the polycarbonate housing with the screws.
