I have a circuit board with a button in it (the clear white button pictured below is the one I'm targeting). I need to somehow remove the button from the circuit and put a relay in it's place. I'm assuming that the easiest way to do so would be to simply connect the ends of the relay to the correct leads of the button, and if I'm not mistaken, the button would simply be shorted out.
Could someone help me in choosing which leads on the relay should be connected to which leads on the button?
Here are the pictures:
If you need any more pictures or info, let me know
edit: I don't have a schematic but here's the bottom of the board with the 4 leads of the button circled:

The button which you have is related to a fairly common family of buttons called B3F. A button like that would usually be Single Pole Single Throw (SPST) Normally Open (NO), as @jrtrzeciak had mentioned above.
It's good that the PCB, which you're dealing with is single-layer. That makes it easy to trace the signals.
I think, the button is connected like this:
Furthermore, if the button is indeed NO, you don't need to remove the button. You can connect the reeds of the relay in parallel with the button. You'll just have 2 switches (relay and button) in parallel.
