I am really perplexed at this moment. I have never encountered a radio installation this challenging. I am attempting to put a radio in my 2002 Camry LE. The vehicle is equipped with a JBL radio without navigation, and the amplifier is located under the glove compartment. I am on my third installation harness that fits properly, yet I have no sound whatsoever. Is there a proper harness available for use? My radio has a single 20-pin connector, but the harness I received contains many more wires than the connector in my vehicle. Enclosed are images of my radio and connectors. The Amazon link for my plug is attached.

I can assist, but I require some questions to be addressed first.

Please confirm that you possess the JBL system, as this is a straightforward resolution. Could you please photograph the front of the old head unit and the amplifier for me?
Did you possess a harness linked to the smaller connector on the OEM radio? Are there control buttons on the steering wheel? Kindly provide a photograph as well.


Would you prefer to circumvent the amplifier or utilise it? Do you wish to maintain your steering controls or not?

What is the brand and model of the new head unit you are installing?

I possess a singular plug on my OEM device, an antenna jack, and an additional tiny antenna-like jack. Absence of steering wheel controls. The amplifier is inconsequential to me, provided that the sound quality is excellent. The radio is a Pioneer DMH-241EX.

I completed this installation on my 2006 Camry this week.

Commencing now. One further inquiry. Do you own the wire harness for the Pioneer DMH-241EX that incorporates the RCA jacks? The image indicates it, although the manual specifies that it is sold separately; therefore, I need confirmation that you have done so.


If you possess that harness, then what you require to purchase is this.

,,METRA 70-8113


While other manufacturers offer similar harnesses, I prefer Metra products. I expended approximately $15.00 on Amazon. The quality is great. Nonetheless, obtain what you desire.

You will solely establish the fundamental power connections and utilise the low-level speaker connections (RCA) for audio transmission through the JBL amplifier.
No speaker cables will be connected to this harness.
To activate the JBL amplifier with the head unit, it is essential to connect the blue and white wires. Otherwise, there will be no audio. You are connecting merely four power wires.

Attach the power cables to the aftermarket head unit.
COLOUR FUNCTION Black Background Yellow Battery/Memory
Red Ignition/Accessory Blue Power Antenna Blue/White Amplifier Activate


Attach the RCA cords to the line outputs of the aftermarket head unit.
COLOUR FUNCTION:

Grey Right Front, White Left Front, Purple Right Rear, Green Left Rear

Only connect the main radio antenna wire to the unit; the smaller plug is not utilised. You may secure it with tape if you choose.

That is all. You will excel.

It is likely that the JBL amplifier surpasses any integrated system within the Pioneer DMH-241EX. The JBL amplifier has an output impedance of 2 Ω, whereas the Pioneer amplifier has an output impedance of 4 Ω. Consequently, when connecting the new head unit to the speaker level wires, it will be necessary to increase the unit's volume to get sufficient sound levels. I will maintain the JBL amplifier attached as demonstrated above.

I trust this information is beneficial. Kindly pose any other enquiries you may have.''
