Normally a quickshifter will just cut spark - although I think some cut injection.
The manufacturer should be able to tell you exactly what needs to done and how their qs works ie either spark or injection cut.
I'm guessing you would probably need to splice into the wires to the coil sticks to cut the spark.
The dynojet qs is different as it just plugs into the powercommander, which is already spliced into the bike.
The TransLogic qs I installed on my SD already had the correct connectors, so all I had to do was unplug the connectors to the coil sticks and re-plug with the qs plugs.
I could probably tell you which wire its cutting as the connectors daisy chain off each other. Let me know if you want this info and I'll check it out when I get home, I may be able to get a photo as well, although its difficult to get a decent one with the crap camera I have.
