OEM JZA80 Supra Clutch Pedal Switch.
These only come on selected JAP delivered supras, I believe all USDM supras came with these.
This is required for your factory cruise control to work. Some models will have this plug tapped up to the body loom, or you can wire up your aftermarket ecu up to this switch.
Note: This product does come in the OEM Toyota packaging, it was just removed for site image.
