how do you trouble shoot a speedometer

Did the speedo ever work? I think you said you got a different cluster and harness. It's all electical, there has to be an open or a loose conecter somewhere in that new harness. The wires are W/BK, GN, BK/Y and Bl that go to the speedo.

Good Luck

yeah the speedo worked......it worked in the original, before i disconnected everything, now when i hook up the original or new one, niether will register?

There is a vehicle speed sensor that is hooked up to the tranny that runs the guage cluster i do believe. It sits on top of the tranny, next to the turbine speed sensor, and no, I am not making up the TSS, it costs $125 for a little 2 pole sensor from Ford that controls whether overdrive kicks in or not.

Well you had a speedo when you pulled the cluster, so the speedo works. If the speedo works then the VSS works, no point in changing any of that. It has to be a wire possibly hooked up loose or crossed with another. Check the cluster wires for continuity.
