Abs/speed sensor on a 1999 4 cylinder Ranger
 

I just recently replaced the ABS speed sensor because the ABS light was on and the O/D light was flashing. Also the speedo would cut in and out. It has slightly fixed the problem. Now it only happens when I hit about 60MPH and I cant find any info on why it would continue to do this or what's next to check. I have cleaned the connections to the sensor and ran the electrical lines back as far as I can and there is breaks or corrosion. Any help given would be greatly appreciated. Thank you in advance.
