Looks like this may be the link you're talking about. Post 27:
http://www.peachparts.com/shopforum/showpost.php?p=2445456&postcount=27 is my install in my W124.
Very happy with the install. Works great. Clean, easy, reliable. What more can you ask for.
No problem attaching to the throttle at all. Very easy. I removed the cruise amp in my install and used that area to mount the bracket to hold the cable. (See pictures for a better explanation) I picked up an dead amp from a member to use the connector for a plug and go install. It works well. I'm even using the VSS from the vehicle so I didn't need to use the one in the kit. Very clean. There is space in the firewall to run the wires under the dash. The stalk works a little bit differently. Up is Resume/Accel, Down is Set/Decel, Off/Off, and pull toward you is now a tap on the brake/disengage, but can be resumed.
