With this accessory, you will unplug the existing wiring harness behind your 12v accessory outlet on your dash, replace that with the power accessory harness and then plug your factory harness plug into the other end.  


There are two leads for power and ground to connect the camera directly.   


You will need a standard crimp tool.  These can be purchased at AutoZone, Walmart, etc.  pretty much any department store or auto parts store.
