I was if anyone had a picture or know where I could get one for a 1998 contour svt. My speedometer has a short or something else I maybe wrong so I'll tell you what it is doing and if I'm a complete moron you can tell me what is really wrong. I was driving along and all of the sudden the needle just drops to zero so I gave the dash a gentle tap ok is was more like a bang but nothing happens. At this point I'm very pissed since I got the car about a month ago. Anyway down the road away it comes back to life and is normal. The whole day it plays this game with me so I had to use the rmps for a speedo. I have had two car that have had problems with the speedo but they were both mechanical and I can tell this is not so the only other thing I could think of that there was a short in the wire somewhere or there is something wrong with the ground. So if you know what is wrong or know where I can get a wire diagram that would be a great help. Sorry for the long post.
Dont have a schematic handy, but check the large connector to the transmission for corrosion. Although it could be in the dash, I think it's more likely to be the connection to the vehicle speed sensor.

Wiring straight forward. Single wire(W/BL) goes from VSS to big electrical connector at driver's strut tower, then it's a (W/BL)wire via connector above fuse panel to instrument cluster.
