I used these to wire lights on a utility trailer.

What would be wrong with using these instead of heat shrink butt splice connectors to make brake wire connections under the trailer? Notice that they are IDC (Insulation Displacing Connectors) and that they are water resistant (they contain what I think is dielectric grease). Notice also that they connect up to 3 wires, as in the situation encountered on the street side connections. I don’t care for the typical IDC connector (usually blue) with the fold over and snap down piece, but these are much better and they are made in the USA by 3M.
