Stock Fog Light Switch to AIR On Board HELP

I realize that this has been started before, some are a couple of years old... None have really helped out all the way due to year of truck, lack of pictures, or wrong info. I'm really close after blowing a number of 10A fuses but would like to finish the job right for future reference for others.

I have a AIR On Board switch that has a constant on Bottom Red LED when the lights are turned on and a Green Top LED for when the fog lights are turned on. The truck is a 2014.

Currently with the below configuration I have both Green and Red LED when the lights are turned on, and Green turns off when fog lights are on.

I've reached this far because of TW, hopefully can finish this off right. Will do full write up when complete.

The middle diagram of the switch is probably accurate for your truck's OEM switch and wiring harness. I'm working on a similar issue in my 2015, as I got a replacement switch (CH4x4) which is intended to be positive switched, but we really need negative switched, so my LEDs aren't working right either. If yours is like mine, the green LED is on when the switch is off because the voltage coming from the relay toward the switch (Pin3 Blue Relay) is driving the LED against the common ground of both LED (Pin2 Gr/wh wire), and it turns off when the switch is on (Pin4 Wh/bk) puts both sides of that LED to ground [see 4th photo below, and excuse poor drawing skill].

I know for my switch I'm going to need to cut some traces and rewire the "ON" LED+ side to the Illum+ with the other LED, and move LED- to the opposite side of the switch from ground (pin4), which I think I can do by splitting what appears to be a DPDT switch wired as SPDT. Or, as long as I'm adding relays for LED bars and mirror heaters, it might be easier to just add one more positive switched relay to close the circuit for the factory negative switched relay...

 

I have an Air On Board switch that I would like to replace my OEM Fog light switch. Going to follow this so hopefully you guys can figure it out

 

Poof

 

Did this ever get done?

 

Yep, sorry for the late reply. Figured out I needed a relay to make it light up properly since the stock switch did not have this function.

I now have a secondary fuse panel and have the fogs wired so they are on their own harness. Always hot.
