We have all been in that situation when we go to use a trailer and there is a broken light or bad wire. Instead of taking the time to do a proper repair you twist some wires together and wrap it in a ball of tape and head down the road hoping that the repair will hold until you get home and can properly repair the trailer.
There is a better way. Using a connector like the 3M155929-ND you can replace a light or install a new wire with no stripping of the wire, no tape, heat shrink or special tools. This is a fully insulated Gel filled connector that you simply insert the cut end of the wire (non stripped) in and clamp down with a mechanics (slip joint ) pliers. The IDC (insulation displacement Contacts) ensures that you get a good connection while leaving the insulation in tact and the gel ensures that you have a moisture resistant connection.
With the 3M155929-ND you can use 2 or 3 wires and it is water resistant either way. It is a wiring essential that should be in every vehicle that pulls a trailer for a quick and effective repair that will last.
Here are some other gel filled connectors that we have here at Digi-Key.
