Quoted from gutz:Yes, they work for system 11 but you have to be careful that you understand the wiring differences, as Chris outlines in his link above.
If I have time this weekend, I will post installed pics on Sorcerer (system 9), and system 11: Pinbot, High Speed, and F-14.
I would be very interested to see your set up in High Speed. I wasn't sure if this was compatible or necessary.
