Just noticed your question.
If you haven't already done the job, the fill is typically done through the low-side valve when using a shop system.
Your low-side should be under the front bumper on the passenger side.
The high-side valve is just on the right as you are facing the car. Just passed the fan shroud.
I've never use a DIY refill kit, but the manual should tell you which side to fill, high or low.
If it does, at least now you now which one is where.
(Please note: Not a mechanic. But have owned several 2001-2003 Ford Focus wagons.)
