I dont know if 05 had a different harness than mine (it shouldnt, the 05-07's should be the same), but I just did this today and my stereo works lol :P Hope this is a bit more clear, I was writing the last on my phone.
The ground wire on the female side of the radio harness is pin number 19. It will be a brown and yellow wire. Pin 2 (live 12v power) is green and yellow. Ignore the part about the green and white wire, you wont be using that.
if the male end of your Kenwood adapter is missing the corresponding plug that goes into pin #19, it will not be grounded. As you can see, mine did not have that. And if the manual says the red wire on the male side of your kenwood is power, it's probably right.
