Hiya guys. I have a 87 GT with a 93 cobra swap, problem is I just installed my aftermarket tachometer because I didn't think my gauge tach was showing the correct RPM, which I was right, and now my speedometer doesn't seem to want to work. My first question is, is there any wire or power supply to the speedometer or does it run off that plug straight into the back of it? Second question, does anyone know of a dealer that sells a different type of gauge cluster that isn't all LED like the ones I've found? Thanks guys I appreciate the help.

 

speedo cable is directly mechanical run from the trans. my guess is the driven gear is wore out

the tach runs off electrical right off the coil

they are completely unrelated

never payed much attention to guge clusters, so i don't know, but try www.latemodelrestoration.com

 

Did you remove the cluster? If so, the cable isn't seated in the speedo correctly.

 

Yes I did remove the cluster, I'll have to check it again. Thanks guys.

 

^^^^^you probably don't have the cable retainer snapped in place correctly
