Question:
I just purchased replacement lights for my boat trailer from you and getting my wiring supplies ready. I am going to run fresh wires throughout including a ground wire. I watched your video where the dielectric grease was put in the plug connector but none was used in the butt splice. I am planning to use the 3M inline scotchlok splice connectors. Is using grease on these connectors and butt splices recommended? What about heat shrink tubing? Excited to get my new LED lights all hooked up but want them to last.

You wouldn't need to use dielectric grease with a butt connector such as part # DW05714 (view video at the 1:16 mark) as electrical tape will work great.
Heat shrinkable tubing such as part # DW05451 will help protect against the elements. It works with 14-18 gauge wire. Most trailer light wiring is 16-gauge. Once you have your wire inside the tubing you can use a heat gun, blow dryer and/or lighter utilize the heat shrinkable tubing. We also offer heat shrink butt connectors part # DW05744-10. (view 3-wire pigtail video at the :35 mark) Dielectric grease isn't necessary.
Using dielectric grease with a quick splice wire connector such as part # SWC501915-1 is just fine. A little dab prior to inserting wires in the quick connect gives a corrosion-resistant barrier. You will still use electrical tape around the quick splice for added protection.
I have included FAQ and videos for you as well.
