included with each MTP. See Figure 1‑2 to wire a connector

The length of exposed wires is critical. Ideal length is
3/16” (5 mm). If the stripped section of wire is longer
than 3/16”, the exposed wires may touch, causing a short
circuit. If the stripped section of wire is shorter, wires can
easily be pulled out even if tightly fastened by the captive
screws.

When making connections from existing audio cables see
Figure 1-3. A mono audio connector consists of the tip and
sleeve. A stereo audio connector consists of the tip, ring,
and sleeve.
