Flash to pass wiring

[Custom Sills]

I have another issue with my 97 GT 4.6, before the flash light was working sometimes but now nit anymore.

I inspected the multi functional switch already, that seem fine for me.

Which cable color is responsible for the flash light and where is the socket?

So, the only pathway between the normal head light function and the "flash to pass" is inside the multi-function switch. Therefore, I’d suspect the issue lies within the switch.
