Hook up 2003 to 2004 retrofit. 

Those of you with 2000, 2001, 2002 or 2003 Walkerjet 

may prefer following hook up:

This hook up eliminates the possibility of not screwing the shackle pin all the way thus creating dangerous situation. With this set up you can not make mistake. Either you are hooked in or not. The used carabiners are tandem stainless steel locking carabiners. If you are interested let me know.
