Power Control Wire?
 

Hey guys,
I'm hooking my kenwood HU (MP919) to the wire harness and discovered one wire I'm not familiar with (coming out of the Kenwood HU). It's blue and white, and listed in the manual as the power control wire. Is this a wire that should get constant juice, for memory purposes? If so, can I tap it into the battery wire that's going into the HU?

Thanks in advance!

Nevermind, I feel a little embarrassed. I figured it out. It's the remote turn on for an amp. Anyway, I'm planning on throwing the head unit in and hooking up 2 amps a sub and replacing the door speakers. I'll post the pics when I'm done.
