But this switch is non-functional - plunger is gone - and the purple and pink are jumpered together. This explains why my PCM thinks the brakes are never applied. I had tuner pro data logging on and I tested this by removing the jumper - brakes registered on. So....I know I need to replace this switch, but I don't know what it's called. Haven't been able to find it on Rock Auto or anywhere else.
In the diagrams it's listed as ABS brake switch.
