05 chrysler 300c head unit

hi, I have an 05 Chrysler 300c with the boston acoustic stereo in it. I just purchased a pioneer avh-x2500bt to install in it. I also purchased the pac rp4-ch11 so that I can keep my factory amp and steering wheel controls. I can get the head unit to turn on but that's it. I don't get any sound which I am assuming that the amp turn on is not hooked up and the steering wheel controls do not work. all I have hooked up is the main harness with the ground,power,and speaker wires. im not sure where to hook in for the amp turn on, the reverse/forward wire,mute wire,vss wire and not sure if I have the 3.5 mm plug in the right place for the pac rp4-ch11. right now it is just going to the aux plug on the back of the head unit. I know its all simple stuff to hook up but I don't want to tap into the wrong wire and do some damage. any help or direction would be greatly appreciated. thanks in advance.

Is there a blue/white wire on the ch11? If so, connect it to the blue/white wire of the deck. I can only guess that the 1/8 inch jack on the ch11 is the steering wheel control output. Connect it to the other 1/8 inch jack on the back of the unit.

I gotta check the wires when I get off work in the morning. I think they are both there but the one on the ch11 doesn't match up with anything on the factory harness. There are 2 3.5mm jacks on the back of the head unit 1 says aux 1 says wired remote.i tried the aux but not the wired remote.

It belongs in the wired remote jack.2007 Jeep Grand Cherokee Overland, Memphis amps and speakers, Pioneer DVD deck.

Thanks that's what I was thinking.just ran outta time today.

Messed around with it a little today and got the amp turning on and the steering wheel controls working. Just gotta neaten things up and ill be done for now.plan on installing some subs later. Thanks for the help.
