Expert Reply:

You can use the Pollack # PK11700 to install on your gooseneck trailer and create a 7 way plug capable of fitting on the 7 pole round plug that is on a semi tractor trailer truck. For the wiring you can use the Deka Jacketed 7 Wire # DW04914-1 which is a jacketed 7 wire sold by the foot that will allow you to connect to your trailer's wiring and the plug.

If you just want to go the adapter route, you can use the # HM47425.
