Car will not start after installing an aftermarket backup camera?

I installed an aftermarket backup camera that received power from the cigarette lighter. It worked fine. I ran the wires for the camera from the trunk to the front on the driver's side. Now the car will not start. The battery is new. I checked the relevant fuses in my opinion. I pulled the battery fuse block off and checked it by visually checking for signs of being blown. I replaced the brake switch. When I get into the car and shut the door, the press brake light comes on. I put on the brake and push the start button, and nothing happens. No accessory lights come on. Headlights work fine. The Dome light works. The brake lights work. I put the fob in the slot and still no luck. The battery was disconnected for a few minutes when I checked the battery fuse block. It was running fine before I messed with it.
