Sorry for the delay
Go to your flywheel housing and usually on the bottom you will see a sender that dives the tach I'm thinking it's toast check it for resistance there should be at least 800 ohms there if there is none then it needs to be replaced have a look and let me know how you do

Speedo is on the backside of the transmission by the yoke and the tach sender is in the flywheel housing at the back of the engine it houses the flywheel. Let me know how you do
