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.

Important Note: Failure to mount the red lead of the power cable kit
directly to the battery may result in severe alternator whine interference.
If severe alternator whine interference is present when the power cable
is properly installed, a power line filter kit, TLN5277_, can be purchased
to reduce the interference.
