>>4323340> cable switch A's are kind of expensive to hack apartPicrel 10 smackers. If it’s an electronic release, often times those work just by bridging 5v and G, but hard to know without looking at the wiring diagram. I have a gx680 with some retarded 8pin din cable release and if you bridge 7 and 8 it fires. Think something along those lines. It’s harder if the electrical system needs you to bring a voltage “high” to fire or something else.
