I am trying to install 2 small LED offroad lights on my bull bar, but I'm having a hard time wrapping my head around the switch wiring. I did my best drawing a diagram of what I think I should do but there are road blocks.


The part on the left I understand because its identical to what I did with the dual horn install. Where I loose my tracks is the path to the switch. On the horns install there was already a switch wire there for me. (running to the old horn)

Its a 5 pin switch and needs 2 grounds, 1 power for led constant, 1 power for the other led when the switch is ON, and 1 last pin I guess runs to the relay.

I've read that there are spots on the cabin fuse box that I could use to power the switch, just not sure where and how to plug in, never done it before.

My questions are:

1. The 2 grounds for the switch, where do I ground them in the cabin?
2. Where do I get constant power for the LED? (only when the key is On)
3. Where do I get power for the LED when the switch is turned on?
4. My switch wire to the Relay, is there anything in between that I missed? Or its just a straight run to the Relay form the switch? (Green color line on my diagram)

Thanks so much for any answers!

Your switch should have a wiring diagram that specifies what connects to each pin. You did not specify who you bought the switch from or who made it so you need that info to complete your diagram. Was you switch included with the LED lights? If so, the company who makes it or sells it should be able to provide a pinout for the switch. If not, get more info from the seller or the manufacturer.

Also you did not specify what type of switch you have.

Do me a favor and take a pic of the back of the switch. These get configure so many different ways. I am pretty sure I know how it goes, but a pic would help.

IF there are 5 connections on the back like I suspect here is how they go:
(Looking at the switch from the back)

8: (Top left) ground for back lighting. Jumper this to pin 7

7: (Top right) Back lighting, jumper to pin 8 then to White white with green stripe on the back of another nearby switch)

6: (Bottom Right) Back Lighting +. Jumpers to Green wire on the back of an adjacent switch.

2: (Middle Left) Power from the fuse block via Add-A Fuse

3: (Lower left) Power out from the switch to the control of your relay.

Ok I think I'm starting to understand a bit more. Inline fuse should be going from batt to the relay, not like in my first pic.

I think the only piece of info I am missing is which color wires to tap into on the existing switch (Parking Sensors) for the LED to glow when the switch is not on.

Also, while I have my console up I wanted to install the Blue Sea USB charger I've had to a while. I just have to run a add a circuit to one of the empty Key fuses correct?

Thanks again,

Bump.

So everything is wired up to the new diagram. But the lights do not turn on. :(

When I opened up the center console, some of the switch blanks had wires connected to them. I decided to use that. Mostly because Add-a-circuit I bought was not a "mini" type, so I couldn't plug into the interior fuse block.

The lower left blank had a Red, White, Green, Green/White. I cut those wires and ran them to the switch. The switch seems to be properly wired because the lower light works when the dash lights are turned on, and responds to the dimmer. The upper light turns on when I push it.

I know the lights work because once I ran the wires into the engine bay, I touched the + and - to the battery and they lit up.

* I do not hear the Relay click when I push the switch. So I though it was a bad relay. I swapped the Relay from my Horns that I know works, and still no light.

I'm kind of lost now. Maybe the Blank switch wires I used do not have a fuse? But then wouldn't the switch not have lights on it when I press it?
