chrysler pacifica integration problem

Hi all! I'm in the process of running aftermarket amps and new speakers/Sub off the stock Infinity RCE amp signal and have a question. Is there a remote turn-on lead? I have downloaded the wiring diagram and have located all the essentials to tap into the signal with a Peripheral SVEN4 but can only locate a keyed accessory (Pink/Orange) wire at the amp. The problem is that I would rather not have my amps running when the stereo is off. Can anyone help with this? I'm very close to completing this project but I'm stumped on how to solve this. All answers are appreciated! Here's a link to the wiring diagram: https://www.the12volt.com/installbay/forum_posts.asp?tid=89201&KW=Pacifica

even with an after market stereo it would do this since the head unit is powered on. Your not going to be drawing any extra power either, because your not actually using the amp, since the head unit wouldnt be powered.rtfm
