Sorry, I can't recall off the top of my head. It may well be that your 86 is electronic, not cable driven. A search should provide the info you need.

behind the gauge cluster is a little plug in but you can follow the cable to the tranny but the only way to see it is to take it apart and i want that to be a last resort

But start at the tranny first and work up. Usually people unhook them to keep the documented mileage off of the odometer. At the transmission is where they usually do it. By the way, how many miles on the car?

Re: speedometer/odemeter doesn't work
86 shouldn't have a cable speedo. And if for some reason your speedo is pegged at top speed it wont work unless you pull it out and shake the needle so it sits at zero again.
