Just had the gearbox replaced... runs sweet. Only problem is the speedo doesn't work anymore. So I tried re-plugging it into the back of the speedo gauge, but nothing. Jacked up the car, slipped into first gear, had a look at the cable and it wasn't turning. So I got under... and removed the other end of the cable:

Is this the problem? I thought the cable should look the same both sides or something? Does the split cause any difference aswell? (guess its not healthy!)
Any help would be great!
