jjjjm2011 :

What year model? I'm seeing the blue/white wires are for illumination only on most models

Customer :

2002 Sonata GLS

jjjjm2011 :

ok standby

Customer :

A wiring schematic shows it as needing to be connected to system control terminal of the power amp or Auto-antenna relay control terminal (max. 300 mA 12 V DC). I don't have an after-market power amp

jjjjm2011 :

This is the wiring diagram for the 2002 model. It does not have an amp in it and requires one to work.

jjjjm2011 :

Car Radio Battery Constant 12v+ Wire: Orange
Car Radio Accessory Switched 12v+ Wire: Yellow
Car Radio Ground Wire: Black
Car Radio Illumination Wire: N/A
Car Stereo Dimmer Wire: N/A
Car Stereo Antenna Trigger: N/A
Car Stereo Amp Trigger Wire: N/A
Car Stereo Amplifier Location: N/A
Car Audio Front Speakers Size: N/A
Car Audio Front Speakers Location: N/A
Left Front Speaker Positive Wire (+): Brown/White

jjjjm2011 :

If this answers your question please accept and leave feedback. Thanks for letting me help

Customer :

Yeah, I have that diagram too. Suggestions? I have power but no sound.

jjjjm2011 :

stand by

Customer :

Thanks. I thought you left.

jjjjm2011 :

did you connect the wires directly to speakers?

Customer :

No, I hooked up a wiring harness to the new stereo so I could plug it directly into the car's connector.

Customer :

The only wire that was not accounted for was the blue/white. It has a piece of paper on the end that says system remote control.

jjjjm2011 :

if you hook directly to the speakers you could bypass the built in car amp or you could try putting the power antenna and amp turn-on wires together. The hyundai forum said to clip unused wires for remote purposes.

Customer :

I saw that. I'll try attaching it to the power antenna plug-in. Hope it doesn't blow up.

jjjjm2011 :

lol me too. Good luck.

Customer :

no luck.

jjjjm2011 :

I'm sorry man I'm out of ideas besides connecting it to an aftermarket amp because maybe your car amp is blown. I will repost your question to see if another expert knows of anything else.

The BLUE / WHITE wire is for AMP Turn On, if you have a Factory or Aftermarket AMP.
The BLUE / WHITE wire supplies 12 Volts + from the New Unit, when the Unit is turned On

 

See if you have a GRAY wire in the Factory Plug
If so what color wire does that GRAY wire match up to on the Adapter Plug you are using

I ended up taking the car back to the audio electronics store with the majority of their work already done. They made one little tweak and gave it back. I put the dashboard back together and now it works. Thanks to both of you for trying to help.

I'd love to find out what they did to make it work....
