Wire Color
The yellow wire controls whether or not the APX VA radio battery charger will be "live" at all times.
Consider the functionality and vehicle battery drain current below during installation.
Standard Wiring to Vehicle Switched A+ – Charging OFF with Vehicle OFF
For installations where the radio may be left in the APX VA with the vehicle's ignition switched
OFF and minimal vehicle battery drain current is important, the standard wiring connection of the
yellow wire to vehicle switched A+ will disable charging.
Optional Wiring to Vehicle A+ – Charging ON with Vehicle OFF
When the radio is left in the APX VA for charging with the vehicle's ignition switched OFF, the
optional wiring connection of the yellow wire to always-live vehicle (A+) will keep the charger ON.
When the operator takes the radio from the APX VA, low vehicle battery drain current will occur.
See (*) below.

3. Cut the long red lead to the desired length (as long as possible so that the
in-line fuse is located as close as practical to the vehicle battery). Then,
after running the lead through the firewall, connect (crimp) it to the plug on
the 2-foot (61 cm) red lead section that was set aside in step 1. Make sure
that the plug and jack in the lead are connected securely together.
4. Cut the yellow lead to the desired length, and then connect it to the supply
side of the fuse box, according to the above table. It is important not to
connect the yellow wire to the red lead.
5. Cut the black lead to the desired length, then connect it to the vehicle
chassis.
It is NOT a good practice to connect the supply cable black lead
directly to the negative (-) battery terminal; the APX VA could be
damaged if there is a malfunction in the vehicle's electrical system.
