When connecting the wire on the new dash light switch to the back of the instrument panel, be sure to leave a little slack in the wire. If pulled tight, a tension is put on the wire which causes the instrument panel light to flicker when driving over rough roads.
When connecting the wire, be sure that it fits into the small slot in the panel (see Fig. 919) provided for this purpose. If the panel is assembled in place so that the edge of the panel presses against the wire, it will cut through the insulation and cause a short circuit.
