For anyone visiting this later on searching for answers that clearly aren't being provided. This car utilizes a CANBUS System. Which cannot be hardwired into as it is a system for all the Electronic Control Units on the vehicle to communicate with each other and needs to be decoded. You must use an adapter with a decoder connected if you want to access Ignition/Accessory 12v, Illumination, etc. otherwise you could wire a custom Ignition 12v wire which is highly unrecommended unless you want a huge project most of you don't have the expertise for and a deck that has no other features.
