Raptor light switch

Fellas, i would like to hook the following switch up to my raptor lights...

$16 Raptor Light Switch for 3rd Gen Tacoma 2015+ Blue Push Button 32mm

https://www.amazon.com/dp/B0B36XV36L
The description says I must use a relay. But doesn't mention what kind or which one. Any idea on how to determine this? Also im not 100% sure of the wiring, but based on the diagram in the description I can figure it out I think....but does anyone have any advice to electrical work of this type? I plan on adding more lighting and switches in the future so im trying to plan like I know what im doing.

Ideally if im daydreaming here I want:
Ditch lights
Rock lights
A light bar up top
And a few Marty mcfly style pod lights on the front mounted on a bumper. Tbd

How can I plan for these additions one at a time? Starting with these raptor lights and this additional switch...

 

Most people just wire the Raptors directly into the DRL or Ign2 with an addafuse, are you going to be turning them on/off on their own a lot?

Description says that because those switches are rated for 3 amps, running driving lights through it without a relay would burn out the switch.
You want a 12v relay - Hella is good but there are a ton of them

$10 Ulincos Auto Relay U1914 with 14AWG Wire Harness, 12V DC 30/40A SPDT 5-Pin (Pack of 2)

available.

Long live the wiring diagram.

This diagram uses the low beam as a source for the trigger - lights will only work if the low beams are on like a fog light. You can change that source to the high beam (addafuse in the fuse box) you've got driving lights.



If you want maximum control you would add this circuit for each set of lights, you may find your dash running out of room for adding switches for everything, there are spod controllers that sort that out.

 

Thanks for the tips. How do I know if I need a 4 or 5 pin relay? What determines that?

 

Either will work for what you need, on a 5 pin you would leave 87a empty.

I purchased a https://caliraisedled.com/products/...q0TtgKXsZ-Lzo9nuv3-3K1R-dN2qEdBwaAow4EALw_wcB for my engine bay for all accessories i added

 

Ok last question for now, and this might be my missing puzzle piece....

As long as my wire size is correct per ampacity allowances...and I do ohms law and blah blah, as long as my draw is less than the fuse I want to put in, im gangster? If I've got an existing 10a fuse, I can just run whatever lighting I want on that fuse, because the lights won't draw more than say, 5a.
That makes sense to me. Should I put a smaller fuse in there, closer to the ampacity draw? And will that fuck anything up, by just putting a smaller fuse in there?

In my world, as long as the wire size is correct, you land it on the right size breaker....like 14g wire can only land on a 15a breaker....12g wire, 20a breaker. You can land larger wires on smaller breakers, but not the other way around. So are fuses kind of like breakers in the automotive world?

As an electrician i want to become well rounded here. Ive got a haynes repair manual and have been looking at wiring diagrams n shit like that, just trying to reach out to people smarter than myself so I can learn more about automotive electrical.

I appreciate everything you guys teach me! Links, pics, stories, any tips are appreciated. And shout out to @vicali , that link was super helpful to learn about automotive relays.
@4ast4orward thanks for the link to that bracket. I see that coming in handy in my near future, that or entire new fuse and relay block holder lol.

 

Led Raptor light will draw a fraction of an amp, so using an add a fuse with a 5amp fuse is perfect, you could use a 10a even, if it ever shorted out it’s going to blow that in a second.

 

I had a 5 pin wired up and it worked for a day, then the next day I go to flick on the bar and the switch isn’t working. Any idea what it could be?
