Do you have a specific question? If not, you should start with Arm On Fire's wiring diagram for the 616 and work from there.
Good day DizzyKungFu.. I have a question you seem to be of the mind and experience to answer. If you have the time and interest, I am wiring a 616/Joe Jedi sound board into my homebrew Sink Tube saber and would like to get any assistance or suggestion for making the build as simple as possible.. yeah, imagine that with sabers and 616's. Thanx for the aid, if any, you can offer. Darth Abominor
