LED stips for bed

Morn all... Wife got me some really nice LED strips for the bed for pop's day yesterday.
Fairly straight forward install... kinda...
The extra wiring that came with it doesnt seem like its going to reach all the way to the batter, so I may need to hit lowes and pick up a longer set.
However, the ends are just bare wire, so a few questions if I may...
Could I create some sort of terminal connector with the wires, instead of trying to wrap bare wire around the post?
Like one of these guys


In addition, is there a "best route" to run the wires if I am going to install them near the side rails in the bed? Like, just down in between the bed and cab and under to the battery, or through the cab tucked under the carpet, throught he firewall?

Never done this before, so looking for some insight.

 

I just read this thread, dude used "1/2 conduit nuts" for a terminal connection: https://www.tacomaworld.com/threads...t-switch.285145/?highlight=under+the+hood+led
