Speedo not working - found the problem and need some advice.

[Chambers]

Hi all, i took my instrument panel out to see if the speedo was damaged, but when i spun the "gear" the speedo was working fine. So i drove the car around my house and the the cable wasnt moving, so i thought it must be the connection to the tranny at first, but then i heard a squeal from the green conector that goes to the speedo so im wondering what should i do now? Any help would be awsome. Thanks!
