At the other end I used a simple 4 wire connector. I also bought an extra female 4 wire connector and cut off the wires and taped up the end. This I\'ll use for a weather cap on the coach loom when the toad is disconnected or I\'m not towing. You can see I\'ve just used the standard 3/8\" plastic wire loom cover. Just a note- when you do this you will have to peel at least one of the wires away so that it fits into the loom cover. You can use those springy/curly trailer wire connectors if you want it really doesn\'t matter. I did it this way only because thats what I had on hand
