Temperature Switch Wiring

[PushnFords]

I was working on a '91 Metro I bought last night and found what appears to be a temperature switch in the passenger side of the intake manifold. It is a small brass sensor with a male spade terminal on it...but no wire in sight. I've looked all over and can't find the wire that goes to it. Can anyone tell me where to look or has a picture?

Thanks,

Derek

Here's a picture of the sensor. If anyone can tell me where the wiring comes from that connects to it I'd be very grateful. Thanks!
