It's like 4 bolts and a couple clicks with a wiring harness. I'd be surprised if they don't splice into your brake lights directly. Go get the wiring harness from Nissan or buy it online, buy the hitch, spend 30 minutes installing it properly in your driveway. Having a hitch installed for you is the first step in surrendering your man card, unless of course you're physically incapable of doing this.

Not necessarily. On my last truck I had the place I bought my hitch from install it (just the hitch, truck already had the trailer plug) because they offered to do it for free. No reason for me to lay under my truck when someone is offering to do it for free.
