You said yours is an SE I'd look into your wiring you might already have it bnicetruck and just need the pigtail going to steering wheel the steering wheel(with controls) and the required relays/fuses from another donor SE that came with it that way you'll have the factory. To my understanding Nissan looks to be pretty liberal or easy meaning to cut down on costs in their vehicles they all start out the same look at it this way a tree has a trunk and branches so other than pigtails(Branches) for different option packages your main harness(Tree trunk) might just be same Id at least take a look
I agree with Sabretooth.
Most vehicles these days are built with all the same wiring in place as it cuts down on manufacturing costs. Then when you pay hundreds extra for options they only had to toss in a $5 part
You may only need to add a harness pigtail (and change your steering wheel if it doesn't have the buttons?). I'd take it apart to have a look & compare it to factory wiring diagrams. Could see it being as easy as swapping in some parts from a wrecker for little cost.
