This is a 3 Pin Connector. Does NOT fit the 4 Pin connector on your GT500 or any other model not listed.
If you replaced your stock exhaust with an aftermarket exhaust this plugs into the wiring harness that goes to the muffler exhaust valve and eliminates the soft error code that appears when the valve is removed/disabled.
You can also disconnect the valve in the open position on your stock exhaust and plug this in to run open all the time.
This comes with small protective plug for the valve on stock exhaust to prevent corrosion on connection.
