Two terminals are the coil. Use your Ohmmeter to determine which two are the coil set ohmmeter on Rx100. You should have a few ohms resistance on the coil. The other three are the contacts. It is a simple single pole double throw switch. The normaly closed contacts should have Zero resistance when measures with your ohmmeter. The normally open contacts will not show any connection at all with the ohmmeter. Once you determine the coil terminals (I would guess that they are 1 & 2) apply 12 volts to the coil and the relay will operate.
One coil terminal will go to ground and the other to your back up switch. The B+ wire will go th the center of the coil switch and your lights will hook to the normally open switch contact.
Hope this helps!
