I'm going to be doing a lighting project however need help with the diagram.

Here's the plan, I want to wire up a 42" Curved Light Bar and a 30" Light Bar to run off the same switch, 2x 3" Fog Lights(Ditch Lights) same switch, 2x 3" Spot lights off the same switch, 12-20x 23mm Egale Eye LEDS(Rock Lights) off a switch and finally 2x 12" Light Bars(Rear Lights) of a switch. Switches will be a SPST 5pin contura rocker switch. I'm not sure if possible, but I would like to run a relay for each set. I'll either put the relays in a Auto Fuse Box 6 Relay Holder or use Waterproof Integrated 12v 40a 4pin Auto Relay and Relay Holder I want to run this all to a dues block(Blue Sea Systems ST Blade ATO/ATC Fuse Block, 6cir w/Cover and Neg.) Not sure if I need a circuit breaker with a large amp relay and fuse tap or not? I plan to use 12AWG throughout, however not sure from battery to fuse block. I plan to use Waterproof Quick Connectors between the wiring and lights, in the event of light failure or upgrade.

Any help and suggestions will be greatly appreciated.

I've got a very similar setup and I've got them all running through a small fuse and relay box with an inline fuse in the cable connecting to the battery. I've got my 42" curved and 40" led bars on separate relays and I have my ditch and fog lights on a single relay then 1 more for some additional spot lights and some leds under the cab. Then 1 more relay for my rear 20" bar and a couple cubes. I've got a 4 pin SPST switch that is made to control 2 separate lights and I've also got some 3 pin lit switches that I had to combine the remote wires from different lights into 1 wire to get the switch to control them both. Hope this helps.

Do you want all the lights to come on at one time, or just the ones wired together to come on at the same time?

With so many lights. Your gonna have thousand relays and wires everywhere.

Ever consider something like this ?

You could easily run more then 1 light of 1 relay. Depending on your volts, amps and such. You simple connect your light positive wire to the wire from relay and you run your switch wire and power wire to where your switches would be.

This is just an idea to keep things clean and easy


Check out my build I have the 10 relay box !

Reasonw why I'm showing this, is you can connect your power wire for switches to one pin and have that switch turn on the relay that will power up 2 lights.

Looking to just have the sets I've named together come on at the same time.

Thanks for the links and gives me ideas. Definitely don't want a rat's nest of wires.

LEDs, correct?
