Hey Derek, thanks for reaching out!
The Hopkins Endurance # HM40157 fits a 1999-2001 Ford F-250/F-350 while the Hopkins Endurance # 40167 fits a 2002-2004 Ford F-250/F-350. So it looks like the plugs are the same, but the wiring pinouts are different and that's why they aren't the exact same wiring kit.
For your 2002 F-350 you need the Wiring Kit # 40167.
Are you looking to start towing a gooseneck or 5th wheel trailer?

Ok. I wasnt sure because the price was so different. Thank you for explaining I have been towing a trailer but running the cord over the tailgate to the plug. This looks so much more convenient
