All the wires you are looking for are in the trunk on the right hand side (Behind the cover). I pulled wires from the head unit to the trunk and spiced into the existing harness. This install will take alot of time. I think I spent most of a Saturday changing out the stereo and speakers.
BTW you will need to make a custom mount for the rear speakers to install 6x9's. The stock speaker is a some strange size that is bigger than 6x9. I used 1/4" plywood to make the adapter.
another question this is about the radio installation i have no power to my radio when i hooked it i hooked up the the yellow and red from the stereo to the yellow cable from the car and hooked up the ground and nothing
