Speed Sensor

Sorry for all of the questions, but i'm learning.

I know my car needs a new speedometer cable. But, the speed sensor on the side of the tranny where the speedometer cable plugs into is not wired up. I don't see any wires hanging down to plug onto the sensor either. What i'm wondering is once i put a new speedometer cable on, will my speedometer work even without the speed sensor being wired? Or can i take the speed sensor off and plug the speedo cable right into the tranny?

Also, would a local shop be able to calibrate my speedometer for the new Saleen 200 MPH white faces with everything in the car, or do i need to take the cluster out and just take them that? Any ideas?

Thanks once again,
Jason
 
I got the cable routed through the firewall and down to the tranny. Now the cable will not plug into the speed sensor. I took the sensor out and looked at it and there's a yellow (looks like plastic)piece inside that sensor and there's no square hole for the speedo cable piece to fit through? What do i do? Get a new speed sensor?
 
The sensor comes with the square hole. It's probably your broken pice of cable in there. I'm not sure if the sensor comes apart or not. Clean it up and see if you can see it better.
 
The sensor should have a clip you needed to remove to pull out the old cable. It is a wire type clip that retains the cable in the sensor. If you didn't take this off, part of your cable is still inside.
 
There's no clip, and the old cable was completely torn off. It was like that when i bought the car. All i see inside that sensor is yellow plastic. So i'm guessing it's stuff still in there. I haven't had any luck taking it apart. I guess i'll have to go to AutoZone and buy a new one. Thanks once again for your help!
