eventually breaking at their connection point. Find a hole part-way

wrap provided in your kit to secure the battery leads in place, as shown
below. Insert the tie-wrap through the hole, close it over the wires,
and pull tight. Nip off the excess end.

mounting holes
(see below). Also, using side cutters, remove the key
tab from the side of each pot prior to installation.
