Tyro 99 build Beginner Need help with receiver!

[Nevemmak]

I have built my tyro 99 and am so excited to fly it but I just cant get the receiver to communicate with the fc at all. Ive tried soldering it in couple different spots, Ive tried looking for the pin which communicates with the receiver to maybe remap the receiver, because I read that in the cli commands you can remap it because the i-bus pad is so small, so right now ive soldered the signal wire to rx4 but cant figure out what pin the receiver is on or the default sbu pin, to maybe I could change the pins. Please I would like some advice asap so i can start flying. Thanks

Good morning Nevemak, did you notice the 3 bridging pads , I have included photos of what to look for, you solder either the middle one to the left one or the middle one to the right one depending which receiver you are using. Hope this helps
