I have a 2008 caliber. I installed a pioneer deck. I needed the wiring harness, interface, and dash kit. But you cant connect red to red because on wire harness that connects to factory red is a dead wire. You have to connect the red wire to the cig lighter or accessory plug in or just connect red and yellow together on your harness to yellow on factory connector, but if you do that radio will stay on even without key in so don't forget to turn off or you will drain battery
