If one could tell me where each of the pins on the back of the camera go to, that would be great. if someone added the code also that would be awesome.
You need to connect A4 and A5 via pullup register to 3V and to I2C interface on Arduino Uno. And you need to connect A7 to XCLK signal via 2 registers.
You can find schema and code in my blog: How to connect Arduino Uno and OV7670
