For Wiring Diagram B installations, remove the Uniden adapter seg- ment at the end of your data cable as shown at left. Snip off the end of the cable protected by the black heat-shrink. At right, we have used clear heat-shrink for clarity, so you can see the diode and resistor pro- tected within. Remove this portion of the cable.

After you've removed the adapter segment, use wire pliers to expose the ends of the five remaining wires in the cable. Cut off the black, blue and white wires, then seal their ends with electrical tape.
