Twist the appropriate wires together, making sure that the exposed
ends make good contact. Secure the wire ends with wire nuts, then
wrap each wire nut securely with electrical tape to protect against
moisture, as shown in the figure on the right.
After taping the wire ends individually, wrap the entire connection
with electrical tape as shown. This will help protect from moisture and
prevent the wires from breaking contact.

Uniden adapter segment of the cable as shown in the following figures.
