Thanks for the picture of the trailer wiring connector you have. Based on that you are in need of a 7-way blade extension like the part # C56080 for a 7 foot long extension or part # HM20049 for an 8 foot long extension.

Or if you are looking for something shorter you'd want the part # TLW6024 which is 24 inches long.

I see what you have now. The second picture didn't initially load but what you have is a Euro style 7-way which covers just trailer lighting functions that is sometimes seen on Range Rovers here in the US.

Answer 7

According to ProGrip, the strap on the ratchet side of the #317-18900 adjusts out to 12' long. The other end with the fixed length strap is 21-1/2" long. You won't have any issues using this on your trailer with a 7' distance between…
