Viper 791VX RS green wire, key side?

Can anybody tell me how to hook up the green wire from the RS relay satellite.  It says to hook it to the key side of the starter wire, but I don't know what that means.  My vehicle is a 1998 Ford F-150 (w/out any kind of theft system -- no PATS, no transponder key, etc.).  I hooked the purple wire from the RS relay satellite to the (red / lt. blue) vehicle starter wire under the steering column, but I have no idea what to do with the green one from the RS relay satellite.  Can anybody help me out.  Thanks in advance.

I am by far not an expert.  When I recently did my 97 Blazer, the instructions said to cut the starter wire after positively identifying it.  Purple gets soldered to the starter side and the green gets soldered to the key side.  You end up connecting them throught the remote start relay.  This is for the antigrind and the starter kill.  Hope this helps.
