Speedometer Sensor

[LuckyHurstGuy]

Hey everyone so I'm doing some work on the gauge cluster and there's this wire with a sensor of some sort at the end that attaches to the back of the speedo. I'm having trouble identifying this can someone help me out?

Thanks

This is a vss vehicle speed sensor

That is for cruise control

And lockup control

Ok cool thanks... my speedo isn't working so does that mean the trans won't lockup now?

It's only needed if you're still running on the computer and also needs to be retained if you're using cruise control ( weather you're on the computer or not ).

So it doesn't do squat for transmission lockup if you ain't running on the computer.
