The switch can be removed without removing the cable assembly if needed and vice a verse.
To remove the switch start in the engine bay by disconnecting the battery, then remove the wires from the switch after noting their positions, then loosen the set screw on the end of the switch shaft that retains the control wire to the switch, then you have work inside the car as you have to remove the nut that retains switch to the firewall. You might have to have someone hold the switch while your remove the nut.
To remove the cable assembly, loosen the set screw on the end of the switch if the switch is still installed, then remove the nut that retains the cable assembly that is on the back side of the dash. When the nut is completely unthreaded from the shaft, you will able to remove the assembly by sliding out the assembly. If possible, try to grab the nut and the washer(s) before you pull the assembly all the way out or the nut and washer might get lost in the crevices of the dashboard. I don't think you have to remove the speedometer head with gauges to do this, but it won't be easy.
Try not to permanently damage your neck and back during the process. It sometimes helps to remove the drivers seat, which in case you did not know will slide right off the tracks without the need of any tools. Simply slide the seat forward until it comes of the tracks and remove the seat from the car. With the seat removed, you can prop up a creaper with wheels removed on the seat tracks and on top of the pedals to support yourself. You might want to use some blankets or rolled up towels to support your neck and head while you are crammed in there.
