That will work.

But the ground on pin 3 is grounding one side of the LED.
Pin 7 grounds the other side of the LED.

May as well connect both ends of the LED to the chassis, the current is not going to flow through the LED.
No, your looking at the color of the wires and not the flow of current. That's twice you have farted here.... The original switch current flow is maintained, look closer...

I am looking at the flow of current.

How is current going to flow between 3 and 7 when you are grounding both 3 and 7 AND there is resistance between them? The current is going to flow to ground from 3.

Because it's exactly as Carlig meant it to be wired....led doesn't lite if not grounded...it makes connection when switch is actuated....T-branch, one side grounds the circuit. the other branch flows to ground via resistor dropping current for led to lite...but you knew that...it's a simple thing not a PLC or any other sophisticated circuit.

WHAT??????????

You are grounding BOTH SIDES of the LED!
Current can NOT flow.

Current follows the path of least resistance, which is from pin 2 to the ground connection at pin 3.

This is not what Carling had in mind. Carling designed the switch to operate using the typical switched-hot circuit common in DIY applications and it is not compatible with ground-true switching.

Here's the entire diagram, as Carling designed the switch to work (fuses and secondary power connections omitted)...




Here is what you are instructing the OP to do... the LED is grounded on BOTH sides because the stock relay is always hot and the switching is ground-true.

YES, REALLY!!!!!!!

Look at the damned switch diagram!

The LED is connected across pins 3 and 7.
If you ground both of them, the LED will have no current flowing through it!

What are you not understanding??????????????

YOUR not understanding that all the OP want's is the switch to indicate circuit ON when actuated, which is what I am showing in my the diagram...

I know what he wants, and what you are instructing him to do will not work, as he has already tried and informed us.


I'm done here. Have fun with the rest of this thread.

Haha I respect your wealth of knowledge for current... But has this been figured out yet? Trying to do the same thing but don't want to mess anything up. I'm in the exact same position as the OP with the anytime Fog mod.

I ended up running all my own wiring to the factory fog lights. I capped and sealed the stock wires.
I ran power off the parking lights. So I now am able to use the switch I bought and I have fog lights anytime (with parking lights on).

Sounds good, wish there was a plug and play. Thanks for the follow up!

i tried this and would not work. you have to re wire the fogs front to back like an aftermarket set. Rich is 100% right.

OP, I hope you don't mind me piggy backing off your thread. Didn't make sense to make a new one since it appears you already resolved your issue & I am getting ready to attempt the same thing but with a different switch.

I ordered a carling switch to replace my OEM switch. I also have the Anytime fog light mod done and wish to keep the same function. My switch is different than the OP's; My switch has 2 leds, bottom to be lighted only when switch is ON, top LED on with parking lights.

Can someone please suggest/tell me where to wire everything from? Will this switch have the same issue as the OP?
Note: My Fog lights are 35W HID's

I was thinking of putting in a led switch for my fogs, till I ran across this thread. Not sure
now!

8 will connect to the green (+) and 7 to green with white tracer (-) used for Toyota's dash lights. This will light up the switch with your dash lights.
