This is SO much easier to use, than having to solder wires together.Used this to hardwire in a tail light on a dirt bike with little room under the seat.Made life so easy!Definitely have a decent heat gun or heat pen that gets decently hot, but be careful not to over heat as the plastic becomes a little too maleable when it is over heated. You can see when the solder melts and fuses the wires together who’s is very nice. I still heat shrank and wrapped my wires for added protection from the elements and to clean up the installation, but overall, extremely pleased and impressed.
