iPod in 2001 Malibu with Pioneer HU

I recently purchased an iPod interface cable that connects to the Pioneer IP Bus Aux port. I've connected the cable to the IP Bus Aux port, and the music plays great from the iPod. However, I did not get the iPod charger to work. That is the red wire on the iPod interface cable and I need help trying to figure out where the 12 Volt red wire connects to??

The existing red 12 Volt wire in the car is connected to the Pioneer head unit. I read online that the Power Antenna (Blue) and Amp-Turn-On (Blue/White) leads carry 12 Volts when the head unit is turned on. I was going to connect the red wire to one of those, but I was kinda scared, not knowing what I am doing, and I did not want to cause a short-circuit.

The product came with no manuals, and is pictured below. The red wire from the iPod cable is connected to an inline fuse holder, with a fuse that has the markings F2AL250V. I do not know how many amps the fuse is. My vehicle is a 2001 Chevrolet Malibu. I have a Pioneer DEH-4600MP head unit. That is connected to the GM Class II Data Bus Interface (GMRC-01).

Any help would be much appreciated!
