ceejones said:Bill welded safety chain loops onto the removable section. Any trailer shop could do the same if you already have the hitch.
I described my 4 pin plug wiring here on 9-5-2013. It still works with no problems nearly a year later. Everything is under the taillights.
I did the get hitch from Bill. I guess the safety chain loops was not an option two years ago. Great thank you.
