1) Remove the helmets’s inside padding on the right side.
2) Drill a 5/16” hole in the right side of the helmet positioned so
that mic will touch the driver’s lips when the boom is installed.
3) Remove the bottom screw and first plastic washer from the
Boom Support.
4) Insert the screw and plastic washer from the inside and
attach to the boom support on the outside of the helmet. Do not
fully tighten yet.
5) Remove the screw, knurled knob and washer. Place the boom
between to two notched washers, align, reassemble and tighten
both screws.
6) Drill two 1/8” holes in the helmet for the cable clamps.
7) Attach the audio connector using the large cable clamp and
rivet with a star washer between the helmet and the clamp.
8) Tuck the lead wire from audio connector inside the helmet
alongside the cable that goes to the harness. Use a cable clamp
to attach both of these cables to the helmet with a rivet.
9) Secure the loose cables by adding a zip tie above their clamp.
This will keep them from slipping when the cable is pulled from
the outside.
