The kit came with everything we needed and all wiring connectors to hook it up. All the wires were labeled and the instructions were very clear. We installed the monitor into the windshield mirror puck, eliminating the mirror, but it was already useless so no real loss. Then we found room for the electronics in a handy void under the glovebox and installed the switch pad on the dash. Now that everything is hooked up we just press a button corresponding to which camera we want and enjoy the view.
