That will work too, you can also just "nix" the crimp connector and solder the 2 wires together, i normally do that ( and add some heat shrink tube on top of the solder spot ) as i keep forgetting getting a cheap crimp tool.
You can probably also use any other screw together wire doodad.
IMO a basis simple soldering iron and a set of various size of heat shrink, like duct tape - CA glue and epoxy glue, something every man should have, along with cable ties ( kit various sizes ) and a cheap multimeter.
I also recommend having a kit of various size little neodymium magnets, these little magnets are strong so nice to have 2 clamping down on something you need to hold in place / glue together.
Of course they will not "grip" to each other thru a 1 " board, but little things they are wonderful.
I have a few round ( disk ) and square ones, all about 10 mm diameter / sides and 4 mm thick, but i think i better get myself one of these assortments too, have used a few over the years, like for holding a body to a RC car ( slow moving scale offroader not super fast cars )
You can of course get much larger ones, but these quickly become insane strong, just these little ones, you can not pull them apart when 2 are stuck together, you need to slide them apart, the really big ones can be lethal.
So can smaller ones not least if you have little kids around that might swallow one
