my friend bought a 91 camaro with a 350 crate motor for 3 grand. and his speedometer does not function. under the dash there is a harnest just hanginf there but it goes no where. any ideas on what or how to fix this problem. its not my car so i would know. also has a 85 or 87 t-5 tranny with a stage three clutch installed if that helps any way posssible..

thank you.

 

The 91 is designed for an electronic speedo, the 85 or 87 for a cable-driven speedo. He'll need to locate a VSS with the proper drive and/or driven gears--and hope that his wiring is still there.
