GWHOLE IDC Connector Boundary Wire Connectors - 3m 314 Wire Connectors, Waterproof Outdoor Electrical Connectors (10 Pack) - Ideal for Underground Fencing, Garden Lighting & Landscape Wiring

Only needed one but for less than what others are asking for a single name brand connector you can have 10 and they are exact duplicates in every respect. I took the original OEM connector apart to make sure and they are exactly the same, even down the gel inside. Both these and OEM ones can be a little tricky to use insofar as making sure you insert the wires to the full extent of the connector openings. It is so easy for one to back itself out while you are working the second wire in. Put one wire in, mark it with edge of your thumbnail then pull it out, measure the depth then mark that depth with tape. Repeat with the second/third wire. This will ensure you have both inserted properly. A standard pair of adjustable pliers moved to the large jaw setting can be used to start the process. Place one side of the plier jaw at the back of the connector and the other in the center of the blue front piece. Give a moderate squeeze to start driving the two internal metal cutting arms through the insulation jackets. If you are not centered on the blue section you will push one side down but not the other. Once you have both sides of the blue front started, change the pliers to the smaller setting and continue squeezing until the front is completely seated in the bottom of the clear case. You can expect to see some gel being ejected at this time.
