Its the neutral safty switch/gear indicator switch, The PCM uses it to perform some diagnostic self tests, & the cam-crank relearn procedure.
It will work without it, but I prefer to use them if possible. |

I threw mine in the trash. Just don't shut the motor off in gear, or it will run funny for 1 time afterwords. Learned by experience.
