then fully remove laser module from head-
stock, pulling wires with it.
5
. Insert new laser module wires up through
hole in headstock, and attach wires to wire
nuts as they were connected in Step 4. Wrap
wires at wire nuts with electrical tape so they

cords together with electrical tape or cable
ties to keep electrical components from being
caught in moving headstock parts.

back into headstock, install light seat in head-
stock, then turn clockwise to secure.
