Setting up Bypass (different wiring setup)

[edit]My internal doorbell chimes looks like the attached photo. It takes 2 sets of paired wires. Blue and Yellow is one set. Black and Red is the other set. I have replaced the transformer with the new ring transformer and the existing push bell works. I had a look a the wires behind the push bell outside and it also takes 2 sets of paired wires. Blue + Yellow is one set. Black + Red is the other set. So, one set of wires goes to the 1 (blue + yellow) and 3 (black + red). The other set of wires went to the 2(blue + yellow) and 3 (black + red). Which wires do I remove and put into the bypass? I haven't installed the ring pro yet. Any help would be appreciated. [/edit]
