Why Is Grease Used in Connection For Installing Trailer Wiring in 2013 Chevy Traverse


On the T wire harness for the 2013 traverse. In the video the guy puts a big glob of grease into the connection socket....why?? never heard of that except for spark plug wires. Thanks,

When making all wiring connections it doesn't hurt to use dielectric grease like part # 11755. This helps prevent corrosion and keep out water and debris. It's not an absolute requirement but it can only help.
