Speedometer Oil and water stock gauges not working
 

New to the forum, Just picked up a 1998 GT w a 2008 motor swap with a Roush SC and the water oil and speedometer don't work. All the other gauges work . Any help is appreciated

Well, FIRST, ask the previous owner if they ever worked after the swap. IF he says
no, then you got some serious work ahead of you...

You'll have to get the schematics and trace out the connections and sensors. The 2008
motor would have a different ECU, and transmission. On the trans, the output sensor would change,
which would be the speedometer. Water and Oil would also be sensors, which go through
the ECU. You can always use gauge pods for readings, putting your own sensors in...
