1999 E300D -W210 Chassis-

I need to replace my evaporater temp sender. I have the part but, I need tips on how doing this, getting the old one out, etc......starting with how to remove the panel under my dash over the pedals. I'm a big guy with a bad back...so it would help if I knew right were to look for the screws that hold it in place.

Is there a diagram online somewhere...showing screw or bolt locations.
