VZ-907 Kenwood In Dash TV

[props7]

I have Kenwood VZ-907 that has a CD changer input, kenwood says only a KDC-C907 can connect to it. I have the KHD-CX910 music keg. I noticed the music keg has a R/L audio outputs which i can can connect to my HU but how can I power up the system. The music keg has an alternate power input but i don't know where to find that cable. I'm assuming i need it if I'm going to connect the MK with R/L outputs.
