Ok I just bought a mini speedometer to clean up my 07 883l I was told to hard wire it to my speed sensor it powers up but didst show my speed or my mileage can you help?

 

What brand/model speedo? Your speed sensor is designed to provide a digital pulse that's read by the bike's ECM and the ECM supplies the digital speed data to the speedo via the data buss. Are you sure this speedo is supposed to be compatible with the OEM sensor?

 

All the paperwork say.it is its a drag specialty mini speedometer

 

Since you still haven't given us the model number of the speedo I can't be of anymore help, but most of the DS electronic speedos I see listed state:

Works with all 95-03 electronic speed sensors
