Its really pretty easy. First you will need to undo the nut and take the bolt out.
After removing the bolt you will have to slide the steering shaft into the firewall about 2-3 inches to separate the shafts enough to slide the sensor off.
Make sure to release the 3 tabs before trying to remove the sensor. They will break if not removed. Then simply slide to sensor off the end. You will have to follow the wires up to find the harness to unplug. Unplug the old and plug in the new. Now reverse the process and enjoy much tighter steering.
In the pics as you can tell I wasnt switching mine, but just pointing it out. Another this too, make sure to lock the steering wheel before starting. Hope this helps!
