Where is the fuel pump relay located on a 1973 Mercedes 450 sl?

I'm going to assume that the location is the same for a 1973 Mercedes 450 SLC. There is a fuse compartment in the passenger side kick-panel...remove the kick-panel and you'll see several relays. The fuel pump relay is in the upper left. When turning the ignition to the second position you should be able to hear a click from the relay even with the kick-panel in place.
