In the picture above there are two wire harnesses. The harness on the right will be included with most new head units. The harness on the left is included with our dash installation kits. When you order a dash kit from our site, we will include the proper harness that connects directly to your vehicle. With this kit you will not need to cut any of your factory (vehicle) wires. This makes it very easy to remove the unit down the road. Also, it keeps you from �cutting� any wires.
