Volvo Repair: 2001 volvo s60, brake light switch, fuse panel

Question
My brake lights are stuck in the "on" position. When I press the brake pedal the only light that works is the center rear window light. At first I thought my brake lights were not work but under closer inspection they are actually constantly on.
I've check all my fuses and even replaced the brake light switch...nothing seems to work.
I was told to check the relay switch for the brake lights located on the rear trunk fuse panel. I have no map of the relay switches for this panel (just a map for the fuses). Therefore, I don't know which switch to check. Is there a diagram I can obtain to give me some direction in this matter? Any help is greatly appreciated.

Thank you,
Mark

Mark, I dont have that information here at home but I do know its located in the left fender trunk  compartment.  I remember that its close to the top of those black relays.  You can take one out at a time and see if lights go out.  If not, then a Volvo Shop will need to help you out.  Roger
