The pairing instructions can be found in the manual, I've linked it below:
http://www.championtarget.com/resources/downloads/new_manuals/40923_WirelessRemoteReleaseSystem.pdf
It is only available as a set.
Yes, this is compatible with the WheelyBird Trap Thrower.
You can find the instructions here: http://www.championtarget.com/resources/downloads/manuals/40923_WirelessRemote_WheelybirdWorkhorse_2LIM_web.pdf
This is only compatible with Champion Workhorse and Post 2017 WheelyBird Traps with removable foot pedal.
Unfortunately this will not work with the EasyBird trap. Champion does make one for the EasyBird, however we do not carry it at this time.
If your footpedal cord has a connector which will allow you to separate the cord in 2 pieces, yes it will.
The receiver portion attaches to the foot pedal connection, replacing the foot pedal, you just remove the foot pedal from trap and install the receiver.
