Alpine IVA-C800, 99 Tahoe

I am puting an Alpine IVA-C800 in-dash tv into my buddy's '99 Tahoe. My question is, there are two wires left to go, a blue and black. Which one goes to the foot brake and which to the parking brake? If anyone can help me with which goes where and what I can do to bypass the e-brake, I would be much obliged.  My second queastion is, he has what I am guessing to be a premium sound system with 6 channels. Can I just hook up the two sets of rear speakers to the set of rear outputs or do I need an adapter of some sort? Thanks in advance for any and all replies.

yes, the post above is correct. anyways, did the head unit NOT come with instructions that tells you what color wire goes where? even if it didnt, it should be printed on the top of the head unit!

anyways, heres a few standard colors for alpine head units incase you cant find the diagram

• yellow - +12v
• red - 12v accessory
• black - ground
• blue/white - remote turn on (for amps)
• blue - power antenna
• white and WHITE/ black - front left speaker + and -
• grey and grey/black - front right speaker + and -
• green and GREEN/ black - rear left speaker + and -
• purple and PURPLE / black - rear right speaker + and -
• ORANGE / white - reverse wire
• WHITE/ pink - monitor control lead
• pink/black - audio interupt (for cell phones)
• yellow/blue - parking brake
• yellow/black - foot brake

good luck

Thanks for all of your help. My buddy got this from a friend, and no it didn't come with instructions. I will trace the blue and black cables back and see what they wires they are tied too. That will probably lead me to the yellow/blue and yellow/black wire that were spoken of. Thanks alot for your help.
