1. Remove the bolt and nut (15mm deep socket) that connects the bottom of the steering column to the intermediate shaft that passes through the firewall. (You may need to turn your wheel to lock to access the nut. Might be wise to make an alignment mark on the shaft)
2. Slide the intermediate shaft towards the firewall. It may feel fairly stiff but it will go.
3. Once the shaft is out of the way, pry out the 3 little plastic tabs that hold the sensor in place and slide the sensor out of the housing.
4. Unplug the wire harness on the old sensor and remove the sensor
5. Plug in the new sensor BEFORE you pop it into place. Trust me on this one!
6. Pop the new sensor into place with the wires at the top. One sidenote here: I found no reference marks, slots, or keys anywhere so I am not sure if it matters how it is aligned. The wires need to be on the top or they won't reach.
7. Reconnect the steering shaft.
