The Nissan N-1 boss kit is the perfect solution for upgrading your steering wheel to a sports wheel. It is compatible with most Nissan models and ensures a SLING BAG CROSSBODY RACING STRAPS smooth installation process. The boss kit comes with a hub adapter and horn connector to make your aftermarket wheel compatible with the Nissan steering column. It also deactivates the airbag warning light.

To install the boss kit first lock your steering wheel and remove the horn ring or centre cover so you can get to the steering column nut. The nut is 19mm so grab your socket + ratchet and undo. Then wiggle the wheel as you do so to try to loosen it up, it might take some work, but dont yank it off.

Now on one of the hicas tabs there should be a black plug going off it (which connected to the standard wheel horn) just slide this thru the hole on the side of the boss kit. Then on the back of the horn button there should be 2 male connectors, just connect the black plug on the boss kit to one of them and then either screw it into something metal like the main 19mm bolt or grab some electrical tape and tape it down to the hub so its hidden.

Now put the horn plug on the boss kit to the horn connector and connect it up, if your horn doesnt work check the resistor & horn connection are both plugged in (refer to pics in blue squares). Next put the hub nut back on and tighten it.
