Hi, I'm installing a Sony CDX270MP stereo to a 2007 Hyundai Sonata. I have most of the wiring done so far, but I'm scratching my head for the blue/white-striped wire on the supplied harness.

Radio Constant 12v+ Wire: Gray (Connects to: YELLOW) (Power direct to battery/memory)
Radio Switched 12v+ Wire: Orange/Black (Connects to: RED) (Power from ignition)
Radio Ground Wire: Black (Connects to: BLACK)
Radio Illumination Wire: Blue
Stereo Dimmer Wire: White/Black
Stereo Antenna Trigger Wire: Green/Black (Connects to: BLUE STRIPED)
Stereo Amp Trigger Wire: Pink/Black
Left Front Speaker Positive Wire (+): Green (Connects to: WHITE)
Left Front Speaker Negative Wire (-): Blue (Connects to: WHITE STRIPED)
Right Front Speaker Positive Wire (+): Gray (Connects to: GRAY)
Right Front Speaker Negative Wire (-): Red/Orange (Connects to: GRAY STRIPED)
Left Rear Speaker Positive Wire (+): Orange (Connects to: GREEN)
Left Rear Speaker Negative Wire (-): Pink (Connects to: GREEN STRIPED)
Right Rear Speaker Positive Wire (+): White (Connects to: PURPLE)
Right Rear Speaker Negative Wire (-): Red (Connects to: PURPLE STRIPED)

You can see that I have four possible wires left: illumination, dimmer, antenna, and amp. I assume the blue/white striped wire connects to the antenna, but I don't want to continue on an assumption. My manual states that this wire connects to "the power antenna (aerial) control lead or power supply lead of antenna (aerial) booster".


I see a note that says if the car has a built-in FM/AM antenna in the rear/side glass, I am to connect the REM OUT lead (b/w striped) to the power terminal of the existing antenna booster.

I am so lost. Help?
