Stuck wiring adjustable BEC to Lumenier PDB

Im a bit stuck on a newbie step. Everything seemed simple until this. Even after looking at diagrams. I got a rough idea but wanted to double check so i don't fry anything. Please help me.

My ESC are little bee 20

The BEC is a RTF 1v-17v adjustable. I understand it needs to be adjusted to 5 volts. Where do i connect it on this PCB? I understand I need to not use a wire sometimes.

Now to adjusting. This may be a really dumb question. I got a cheapo multimeter.

Im assuming ill be measuring with the leads in these spots with meter set to DCv as show trying to get it at 5v right? I was adjusting it seeing what it would read(yes im a noob) connecting to those spots and I couldnt quite get a steady reading so i would guess the obvious is it needs the battery hooked in. Would anyone kindly talk to me like im a child and help :)

Not quite. The red test lead should always be connected to the positive (+) terminal and the black should be connected to the negative (-). The IN should be coming from your battery and the OUT is the output voltage (look at the bottom of your BEC, it has the proper labels).

This is correct.

Yes, reading voltage without a battery or power source connected is useless. Think of voltage like water pressure and the battery as a well or some other water source. Without the battery/well connected you effectively have zero voltage/pressure.
