I would be happy to help you make a 5' long 6-way round to 4-way flat adapter, but the longest premade adapter offered in this combination is the Hopkins Endurance Flex Trailer Connector Adapter w/ LED Circuit Tester - 6-Pole to 4-Pole # HM47320 which is only 5" long.

To start you will need a trailer end 6-way connector # PK11604 and 5' of # DW04923-1. The # DW04923-1 is sold in a quantity of 1' so for 5' you will need to order a quantity of 5. You will need to make the following connections with the small pin on the end of the 6-way connector facing straight up and facing you:

Brown wire to 12 o'clock pin
Yellow wire to 7 o'clock pin
Green wire to 5 o'clock pin
White wire to 9 o'clock pin.

Now you will need the vehicle end 4-way connector # HM48190 and make the following connections:

White wire to ground pin (only pin with metal exposed)
Brown wire to the next pin
Yellow wire to the next pin
Green wire to the next pin

This will give you a fully functional 6-way to 4-way adapter. You could also order a longer or shorter length of wire to match your exact needs.

I included a diagram of a 6-way and 4-way connector and a link to a helpful article on wiring for you to take a look at.
