A boat trailer I am going to pull has a fift wire required to release the brakes when backing up. Witch terminal in a seven wire plug EB or auxiliary?

The fifth wire that allows you to back up a boat trailer is the reverse function. Sending signal from the reverse function will allow the solenoid to disengage the surge brake function electrically. The reverse function is found in the center of the 7-way connector. I've attached a diagram to help.
