Configuration B:
The voice / navigation positive and negative audio leads are present
in the primary 20-pin connector in pins 16 and 17 of the
factory radio connector. Config. B applications will only have provisions for one of the 20-pin connectors at the radio. The
additional 20-pin male and female connection will not be used.
Connect the 2-pin connector labeled "B" to the 2-pin connector labeled "To Amp PRO".
The voice / navigation positive and negative audio leads are present in the primary 20-pin connector in pins 16 and 17 of the
factory radio connector. This can be verified by plugging the primary 20-pin connector (see Config B diagram above) from
the radio harness into the AP4-TY11 primary 20-pin connector then looking for wires in pin positions 16 and 17 on the factory
harness side. Pins 16 and 17 will be the same pins that you find the White / Red and White / Blue wires on the AP4-TY11
side of the harness. If there are no wires in these pin locations on the factory harness, Config B is not the correct one for the
vehicle.
Connect the 2-pin connector labeled "B" to the 2-pin connector labeled "To Amp PRO" (See Config B diagram above). The
Brown "Mute Input from Navigation" wire from the AP4-TY11 harness will not be used for this configuration.

Configuration C:
This configuration requires manually wiring the harness with connector labeled "C" into either the Multi-Display (separate
radio / HVAC display screen) harness or the outputs at the
navigation module depending on the year, make and model
of the vehicle (refer to the vehicle chart on pages 2 - 4).
For this reason, we have divided Config C into 3 different
versions.

Config C, Version 1:
The voice / navigation audio
leads are present in the 28-pin connector located
behind the
Multi-Display. Connect the loose 2 pin
harness labeled "C" to the 2 pin connector labeled
"To Amp PRO". Next, locate the 28-pin Multi-Display
connector (at the back of the separate radio / HVAC
display screen). Connect the White / Blue wire from the
"C" harness into the wire that is in pin 21 and connect
the White / Red wire from the "C" harness to the wire
that is in pin 22 of the 28-pin Multi-Display connector.
Refer to the Vehicle Connections Chart starting on
page 2 for specific wire color information. The Brown
"Mute Input from Navigation" wire from the AP4-TY11
harness will not be used for this configuration.
