Cleaning electrical pigtails. What do you think?

[In The Ten Ring]

I'm going to try this procedure this week on my front end pigtails.

Questions:

1). What do you guys think?

2). Dielectric grease is suggested here as a moisture barrier....is that a good idea?

I use dielectric grease on connections a lot. It will help prevent corrosion. My rule of thumb: if it's in a wet location use grease, if it's dry don't.

The main issue with the trailer pigtail is that its behind the vehicle & catches all of the road "slurry" during rain or snow. If your lights are on the brown wire is always hot, making it turn green much faster. If you tow often simply connecting & disconnecting keep it clean, if you don't, pack it with grease.
