Anyone using Lokar kickdown cable?

Aaron and I just installed Lokar throttle and kickdown cables in his Duster today. The instruction sheet for the kickdown says to adjust it so that when the throttle is wide open the cable has no slack.

As I see it, "no slack" in the cable does nothing to pull the throttle pressure lever back on the transmission. Is anyone using a Lokar cable on a 727, and can you tell me how you have it adjusted for proper shifting?
