MAKE CONNECTIONS (refer to wiring diagram)
STEP 1
If using head unit adapter (sold separately), connect WJL2
harness to adapter and skip to step 2.
• Locate the aftermarket radio’s main harness.
• Cut and remove the black 20 pin connector from the WJL2
T-harness and connect the wires, shown in the wiring
diagram, from aftermarket radio main harness to the WJL2
T-harness and match the wire functions.
Note: only connect purple/white wire to radio reverse input or
module damage will occur.
STEP 2
• Determine if the vehicle has a factory amplifier. Look for
badges on the door panels and dash that indicate the
presence of an amplifier (ex: Alpine).
If the vehicle DOES NOT have a factory amplifier:
• Plug the female GREEN connector to the male GREEN
connector of your WJL2 T-harness.
• Plug the female WHITE connector to the male WHITE
connector of your WJL2 T-harness.
If the vehicle DOES have a factory amplifier:
• Plug the female GREEN connector to the male WHITE
connector of your WJL2 T-harness.
• Plug the female WHITE connector to the male GREEN
connector of your WJL2 T-harness.
Connect the factory harness to the WJL2 T-harness.
STEP 3
• Route the 2-pin OBD2 connector from the glove box to the
radio location and connect it to the WJL2 T-harness.
• Locate the green CAN junction block in the glove box cavity.
Disconnect any of the 2-pin connectors and connect it to
the 2-pin female plug on the extension harness. Then
connect the male end back into the green CAN junction
block
STEP 4
• Connect the supplied antenna adapter to the factory
antenna connection. Make sure the blue wire of the
antenna adapter is connected to the blue or blue/white
from the aftermarket radio.
STEP 5
• Route the media adapter connections through the dash to
the radio cavity.
• Reconnect the harnesses to the back of the lower dash
panel. Snap it into place and secure it with the one (1)
Phillips screw.
STEP 6
• Plug the harnesses into the aftermarket radio.
• Plug the antenna adapter cable into the aftermarket radio.
• Plug the media hub cables into the aftermarket radio.
• Plug the 4-pin Data cable to the data port of the
aftermarket radio.
• Insert the Audio cable into the iDatalink 3.5 mm audio jack
of the aftermarket radio.
Note: When using a Pioneer radio, connect the 3-pin black
audio cable to the radio’s AUX input. Do NOT connect
anything to the W/R port on the radio.
STEP 7
• Connect all the harnesses to the Maestro RR module.
STEP 8
Install the aftermarket radio and WJL2 kit into the dash,
then test your installation:
• Secure the aftermarket radio into the dash cavity using the
four (4) Phillips screws removed earlier.
• Install the WJL2 bezel into the dash, making sure the clips
snap into place. Secure it with the two (2) Phillips screws
removed earlier.
• Reconnect the climate control panel harnesses and snap
it into place.
• Reinstall the glove box, making sure the two lower clips
are snapped in place. Then, reconnect the control arm
and lift the glove box back in place.

TROUBLESHOOTING TABLE
PROBLEM SOLUTION
Gauges do not work, radio shows OBD2 Error 1 or Error 2. Ensure the 2-pin CAN extension harness is securely attached to the green
CAN junction block behind glove box.
Reset the RR.
When making a phone call you cannot hear the call, but the caller can hear
you.
Make sure that the 4-pin green and white connectors in the harness are
plugged in correctly as stated in step 2.
The radio doesn’t turn ON at all. If you have a multimeter, turn the key on and check for DC voltage at the
maestro’s heavy gauge 3-pin plug (red, yellow, and black wires). The Maestro
must be plugged in to get an accurate measurement. If there is 12 volts on
the red and yellow, the Maestro is working correctly and sending power out
to turn on the radio. If no voltage on either, check the inline fuse and then
the vehicle’s fuse for the radio circuit.
If front speakers have been replaced, ensure the wiring harness on the left
front speaker assembly has been reconnected. CAN passes through this
connector to get to the radio.
The radio illumination or other functionality isn’t working. Ensure the 2-pin CAN extension harness is securely attached to the green
CAN junction block behind glove box.
Radio displays "Sensor Error. Please contact your dealer or Pioneer Service
Center.
Mount radio chassis horizontally, not vertically. The gyro in the chassis will
not function if mounted vertically.
The light on the Maestro is blinking RED TWICE and the radio IS turning ON. Ensure the 4-pin data cable is connected between the radio and the RR, and
that it is plugged into the black port on the Maestro RR. The red and blue
ports on the RR should be empty.
Make sure the correct radio model and serial number were entered during
the flash. Verify the radio’s serial number entered during the flash matches
what is listed on the radio screen. This can be found in the settings of the
radio, listed as Device Id, Device Number, or Serial Number.
The light on the Maestro is blinking RED TWICE but the radio is NOT turning
on.
If installing a modular radio and it is not turning on, ensure the screen is
secured and any trim pieces on the radio have been installed fully. Not
installing these fully will prevent radio from powering up and show a 2x red
error.
The light on the Maestro is flashing RED ONCE. There is no firmware on the module; flash the RR module.
MAESTRO RR RESET PROCEDURE:
Turn the key to the OFF position, then disconnect all connectors from the module.
Press and hold the module’s programming button and connect all the connectors back to the module. Wait, the module’s LED will flash RED rapidly (this may
take up to 10 seconds).
Release the programming button. Wait, the LED will turn solid GREEN for 2 seconds to show the reset was successful.

IMPORTANT: To ensure proper operation, the aftermarket radio needs to have the latest firmware from the manufacturer. Please visit the radio
manufacturer’s website and look for any updates pertaining to your radio.

plugged in correctly as stated in step 2.
The radio doesn’t turn ON at all. If you have a multimeter, turn the key on and check for DC voltage at the
maestro’s heavy gauge 3-pin plug (red, yellow, and black wires). The Maestro
must be plugged in to get an accurate measurement. If there is 12 volts on
the red and yellow, the Maestro is working correctly and sending power out
to turn on the radio. If no voltage on either, check the inline fuse and then
the vehicle’s fuse for the radio circuit.
If front speakers have been replaced, ensure the wiring harness on the left
front speaker assembly has been reconnected. CAN passes through this
connector to get to the radio.
The radio illumination or other functionality isn’t working. Ensure the 2-pin CAN extension harness is securely attached to the green
CAN junction block behind glove box.
Radio displays "Sensor Error. Please contact your dealer or Pioneer Service
Center.
Mount radio chassis horizontally, not vertically. The gyro in the chassis will
not function if mounted vertically.
The light on the Maestro is blinking RED TWICE and the radio IS turning ON. Ensure the 4-pin data cable is connected between the radio and the RR, and
that it is plugged into the black port on the Maestro RR. The red and blue
ports on the RR should be empty.
Make sure the correct radio model and serial number were entered during
the flash. Verify the radio’s serial number entered during the flash matches
what is listed on the radio screen. This can be found in the settings of the
radio, listed as Device Id, Device Number, or Serial Number.
The light on the Maestro is blinking RED TWICE but the radio is NOT turning
on.
If installing a modular radio and it is not turning on, ensure the screen is
secured and any trim pieces on the radio have been installed fully. Not
installing these fully will prevent radio from powering up and show a 2x red
error.
The light on the Maestro is flashing RED ONCE. There is no firmware on the module; flash the RR module.
MAESTRO RR RESET PROCEDURE:
Turn the key to the OFF position, then disconnect all connectors from the module.
Press and hold the module’s programming button and connect all the connectors back to the module. Wait, the module’s LED will flash RED rapidly (this may
take up to 10 seconds).
Release the programming button. Wait, the LED will turn solid GREEN for 2 seconds to show the reset was successful.
