Hello Sam, welcome to the forums. 2 things, you should post questions about your S Type in the proper "S Type Section". Second I don't know if this will help but on a 2005 S Type the low side is located in the front drivers side (US Version) wheel well to the rear of the tire. It is visable without having to remove the wheel.

Hope that helps.
