Coustik 400S amp problem.?

It's a little trickier than just a harness in this vehicle. The factory radio is tied into the vehicle data bus, and it generates all audible warning chimes in your car. That means if you remove the factory radio you'll lose your door chime, light-left-on chimes, and any other warning chimes. Also, the vehicle data bus system controls the on/off function of the radio, so there's no "accessory" power wire in the harness that an aftermarket radio needs.

You cannot use the red wire in this harness; you'll need to find an alternate source for your accessory power connection. I often use the heavy brown wire from the key switch; it's easy to get to with the factory radio removed.
