installing a Pioneer AVICZ2 GPS wireing help!

[bonzaiii]

I'm installing a Pioneer AVICZ2 GPS unit and just opened my my GMOS 04 harness and was looking through the instructions and the second step is to connect the red wire coming from the 24 pin adapter to the radios Ignition wire, the problem is the 24 pin adaptor does not have a red wire coming from it ? Am I just not understanding something or did they forget to put the wire in, can I add it myself and if so where as there do not seem to be any empty pins on the 24 pin adaptor ? Except for this step everything seems to be very easy and straight forward.
