I have a garage door opener that is like yours. It has two wires but it sends a signal to the opener. I did the (solder two wires) to the internal push button of the wall switch. In my case I was trying to use a secondary internet based service to control my door. It worked fine.
You didn't specify which relays those are, what specific switch it is, where to get them, or give an image of a wiring diagram for download. Even better would be written instructions step by step saying what terminal gets hooked up to what. Also,what does this cost? Also, you'd need a picture of the relays with their wiring diagram that's printed on them so people know which number in the diagram corresponds to what on the relays, and you'd need a number for the switch terminals.
