Because FSRs are basically resistors, they are non-polarized. That means you can connect them up 'either way'a and they'll work just fine!
FSRs are often a polymer with conductive material silk-screened on. That means they're plastic and the connection tab is crimped on somewhat delicate material. The best way to connect to these is to simply plug them into a breadboard.
or use a clamp-style connector like alligator clips, or a female header.
or a terminal block such as Phoenix #1881448
It is possible to solder onto the tabs but you must be very fast because if your iron is not good quality or you dally even a few seconds, you will melt the plastic and ruin the FSR! Don't attempt to solder directly to your FSR unless you are absolutely sure you have the skills to do so.
