2005 300c, aftermarket HUs not powering

Currently doing an install in a 2005 Chrysler 300c, and can't get any aftermarket radios to power. I believe the problem is in the wiring harnesses, and them not being the correct one. I tried multiple HUs, so I know the problem isn't with the HU. I tried an American International wiring harness, CWH-638, and it didn't work (this is the one AI said to use). I looked in the Metra catalog and it says n/a for harness into car. Is there not currently one made for the 05 300c? If I have to tap into the stock wiring harness, what are the wire codes?

did you check if you have 12v , acc and ground

Do you mean on the factory radio? Or if it was hooked up on the harness?    I had it all hooked up w/ teh harness, but I'm not sure if the stock wiring has those.

Those cars supposedly don't have an accessory wire, everything is controlled digitally, like the GM vehicles. Jazzy

So how do I hardwire it?

To hardwire obtain the wires at the following locations: 12 Volts-gray/lt. green at the radio harness Ground-BLACK/ lt. green at the radio harness Accessory-obtain at the cigarette lighter below radio. Also retains radio on until door opened feature when wired here.Five Star Motoring

What color is the acc wire?

I also can't seem to find any correct wiring diagrams for the car. Anyone know what the rest of the wires at teh radio harness are?

Acc Wire- RED / orange at cigarette lighter LF+ gray/purple LF- gray / YELLOW RF+ dk. GREEN/ purple RF- dk. GREEN/ YELLOW LR+ dk. GREEN/ tan LR- dk. GREEN/ gray RR+ dk. GREEN/ brown RR- yellow/gray On base systems wires are behind radio, on higher end systems, wires are at factory amp to the left of the steering column.Five Star Motoring
