After changing my clutch I noticed my speedometer stopped working. Im debating whether it has anything to do with me accidentaly loosening a fuse in the fuse box, or i just forgot to plug back in a sensor??

 

its probably a good place to start doing what u just said. check ur fuses and wiring ****. if not, perhaps take the gauge cluster apart (it comes apart fairly easily) and see if anything is hanging the needle up and stopping it from moving. other than that IDK
