Sanity check on wiring diagram

Installing offroad flood/fog on 2019 Ranger Lariat.

My desire for STEEZ might have outdone my logic. I don't know if this is even possible with the equipment I purchased. I would like all 6 lights on one switch. I am absolutely terrible with understanding electrical components. Might as well be trying to get a coon dog to pass a peach seed. Any advice is appreciated before I ruin my truck or set this bad larry on fire. Thanks for the help everyone.

First you’re at 1050 watts and your switch is rated at 720 watts max. You really should just use 2 lights per switch for reliability reasons. I also think 8 gauge wire is too small to run all 5 of them.

1050 W at 12V is 87.5 amps...should be a 6 gauge wire to handle that current...

Actually he is at 1260 watts, he shows 6 lights. Which is, if my math is right 105 amps. This not happening.

Is that 210 watts actual watts or equivalent LED light output? I don't think that they actually require 210 watts each of input power. 210 watts at 12 VDC would be 17.5 amps. 17.5 amps times 6 lamps would be 105 amps. The switch box you show is rated at 60 amps. I think you need to know the actual amps that one light requires to know the answer.

Well you’re not hosed yet. You could run 3 separate relay coil circuits controlled by a 4th relay via a single switch. That’s way doable. Then the question remains is can your alternator handle the added current load? I’m thinking no without an upgrade.

Amps is watts/voltage.
210w/12v= 17.5a each.
17.5 x6 = 105amps.

You have the option to run 1 continuous use solenoid, with a lot of heavy gauge wire. Or, use a standard relay for each pair, and lighter gauge wire. No need for the fancy switch if this is all you will use. Any plans for future accessories that would require that switch panel? Do you want the lights to only work if the ignition is on?

This right here. For the heavy gage wire get a high strand count as it’ll be more supple and easier to work with.

This is the way.

It is not all I want to add. But if it is going to overcomplicate things I may move on to a different set up. There is future stuff down the road so I am not afraid to upgrade alternator.

I have a very similar gang switch as you posted. 6 switch, six fuses six relays. If you open up the relay/fuse box you can remove all the relays and then see how they are wired. each relay and fuse is its own circuit except. Mine came with what I thought was one solid power wire in to the box. but it was a bundle of individual wires. id bet thats how yours is to. I took mine apart and removed the small power wires coming in and the small ground coming out and replaced them with 4 gauge. i think someplace around r5g has a thread about it with me asking for input and a few pictures of what i changed. I left all the other wires as it came, replaced the relays and fuses as it came and it works great. I would not run all six lights from one button dont do it lol. you could do them in pairs as someone else stated. one pair per switch. I know the all on one button is convenient but pushing three buttons on these type of switches is really pretty easy. you can make the top three those six light so its easy to get them all in one swipe. mine runs 9 lights total and will run them fine all at one time but mine do not require as much juice as yours do. If if you have a way to test the lights hook one up and see what they really take. id bet the advertised power numbers are a bit hyped to make the lights see more powerful.

sorry about the typos. for some reason the page will not let me edit posts.

As long as the switch panel is used only as a trigger mechanism your only limit is how many relays and how big a wire you can manage in the area you are wanting to work.

My Feniex mini-400 panels can only handle 20A total and 3.5A per channel (6) with its internally fused factory components, so I only use it as a trigger mechanism for each individual relay I've installed.

Also, if those lights are from Amazon, chances are they aren't anywhere close to the advertised power draw. 3/4 if you are lucky and 1/2 is the norm.

I guess the kit he is looking at is using under sized relays or something.

6 standard relays would be 150AMP capable (25 per).

All the switch panel should do is send a trigger signal to the trigger channel on the relay. A trigger line only takes like a couple of watts to open it up, basically nothing.

People who actually send power through their switches, why would you do that.

ALWAYS send power to the relay and out the relay. I don't care if a light is only 10A, power it via relay, not switch.

So I actually tested the draw on these lights. What I posted was what the marketing said. However after testing them the reality is they draw about 30 watts each on the 12.2v system. Meaning it's only like 15 amps and 180 watts for the whole system. So if anyone is interested in these lights that's the truth. Making this a much more doable set up.

Bigger wire.
