Dielectric grease is basically just applied in a thin coating to the connector plug. You can use # 11755 or # LT37534 if you prefer a smaller amount. I've attached a video to assist. Just like the connection on the back, you can add this to the trailer pins on the front of the connector as well to keep moisture and debris out to prevent corrosion. I've attached an article to help as well.
