Kickdown help!

Hello once again folks. I just rebuilt my tranny and was wondering if anyone had pics or any info on how to install a kickdown assembly. I have a C-4 mounted on a 289, and I can't seem to get the right answer. And also what does the kickdown do exactly? Any help would greatly be appreciated. Thanks guys.:shrug:
 
Are you working on a 67 or prior? The kick down is a cable that reaches from the trans to the accelerator pedal, 'under' the car. If you are used to a 68 or newer 302/351, you might be thinking of the rod that comes up from the trans and bolts to the carb. There is an illustration in the Ford repair manuals...
