Chevy & GMC Vans

Hi, I am going to install some small recessed lights in the ceiling, and need to wire them in parallel. Everything else is wired up with solder etc, but I do not know the proper way to do these. Should I strip the middle of 1 long main wire and solder in a piece perpendicular to this like below, or should I forgo solder and buy some clips from a local marine store? Just looking for the correct way to wire them up in the van. Thanks

You can/should wire them in parallel if they are each designed for 12v operation.
Please put a fuse in the circuit, and preferably at the power source.

I will have a fuse as it is going to a fuse block, but for LEDs a lot of people go straight to the battery. I installed a dual battery system awhile ago, just upgrading/re-wiring, but I am basically an electrical noob, so appreciate the comment.

I am really just looking for a pic of how to connect the wires, but the terms I am using with Google are not working...only a few pics of the yellow caps that screw the wires together often used in house ceilings....must be a better method with a camper van I would think....I will probably just pick up some clips from West Marine, it is just some LED lights, not a big deal I suppose.
