SOLVED: 09 Ford Ranger speedometer not working properly

Detail: I have a problem with my speedometer not functioning right. I think it started when i drove through a bunch of puddles. The speedometer starts off not working at all. After driving a while it starts to fluctuate a lot and sometimes after 10 miles or so it starts working again. I just replaced the PCM speed sensor and i'm still having the same problems. I'm going to check the wiring tonight but if someone has a better idea or a solution that would be greatly appreciated.
