If you are needing to determine the wire functions on your 2004 Nissan Frontier, I recommend testing them each for function with a circuit tester like # PTW2993. Vehicle manufacturers tend to switch the wire colors they use so going by color alone is not always the best method. You can have a buddy sit in the vehicle and activate each function while you test the wires.
I have attached a wiring diagram of how a typical vehicle-side 7-Way connector will be wired that you can use for reference.
