need help: foglight indicator - where are the wires? - Toyota Yaris Forums

The more I look at this issue, I think that the switch is the issue. The OEM stalk switch is just a switch, connecting pins 3 and 4 on D4. The OEM console switch has the switch isolated from the leds. In the picture of the guts of your switch on that DIY, the switch LED is part of the switch circuit. I think that is what is causing the headaches.

I would modify the switch as follows:

1. Cut the marked trace.
2. Remove the diode.
3. Solder the two jumper wires as indicated.
4. If the pads for the switch are bridged together (where the word "switch" is between two sets of 3 pads), separate them. The switch is a dual pole switch, which allows it to separately switch the two circuits.
