Help with Speedometer cable

[Ghernandez66]

So here is the deal I'm having trouble making my speedometer to work it used to work before I took my cab out for repairs and once I installed it back it don't work no of more. I just changed my cluster last week for a refurbished one from Fred's truck parts and tried to get it to work but I'm not sure if there is a specific way to install it because even bough a new cable thinking mine was bad but still can't get it to work.
Can someone please help with this I have a total of 3 cables can't seem to make any of them work so I know I'm doing something wrong.
Last one I installed I installed it to the transmission first then to the dash.

Any help is appreciated thanks guys.
