Wireless Pickle Jack Connector Styles

Most traffic light control boxes use a 3-connector style jack, but a few use a 2-connector style jack.  If you are unsure which style your boxes use, you can find out by inspecting a cable that you currently use with the boxes.  

Examine your current cable.  If it has two black stripes, like the image on the left , you should order the 3-connector version of the wireless pickle.  If it has only one black stripe, as in the image on the right , you will want to order the 2-connector version of the wireless pickle
