abs speed sensor issue

[drtystroker2005]

my 2005 ford f350 diesel recently the speedometer started acting up , i would be driving and the gauge would cut out and all of the sudden jump back up, i hooked up my programmer to read the trouble code in which it showed speed sensor error. so i bought the part at ford installed it my self and the speedometer is still not working along with the abs light being on too. im not sure what else to do with it. any suggestions
