Splicing a mini plug to use as a trigger is fairly easy.
Just make sure you strip back plenty of wire on the mini-plug. The wires are so fine that unless you have quite a bit to wrap around they are likely to break.
Many pre/pros also require that you dictate when the trigger is in use. THis is very useful for setting up elaborate systems. Check the menu of the pre/pro to see settings for trigger outputs.
Also double check to see that you haven't connected to the trigger INPUT of the pre/pro.
Good luck!
