My odometer and speedometer don't work

What is your question?

I have replaced my vehicle speed sensor and my transmission speed sensor but m speedometer and odometer gauges do not work. My sensors are communicating with the cars computer but does not work on my gauges have any idea what it might be ?

How long has your 1997 Ford Thunderbird had this problem?

About two weeks cause the speedometer fluctuated off and on, but when we replaced the transmission speed sensor it stopped working all together. The odometer never worked to my knowledge.
