So I have a 86 rx7and my speedometer is not working. I was just wondering what is more common to go first the gauge or the cable? My Cruz Control is not working as well but I am pretty sure that it is tied into the speedometer problem. If you know what is wrong please let me know.
Thanks

 

check the cable that screws onto the tranny.they get yanked/pulled out sometimes or vibrates off.

 

Thanks bro! I'll Check it out.
