I converted a PS-1 Premier Blue Comet Pacific about 6 months ago to PS-2. The procedure is the same and it wasn't difficult. This was the first time I had ever attempted something like this. If you decide to do yourself here are a few tips: Make sure the solder joints on the female harness connector are ground down to reduce the profile. This is discussed in the magazine article, I found out the hard way. Don't forget you may have to adjust the air gap between the sensor and the motor flywheel, this is a lot more difficult than described in the instructions. I recommend you measure the gap and purchase an extra sensor already soldered to the proper gap. I ruined my first one and contacted MTH and purchased what I needed. Lastly, make sure you print out the directions in color, instructions will make more sense. If I was successful anyone can do it!
