Now i have no mph readings or odometer as well. what shoould i look for bad speedo cable?

personally I'd look for a melted speedo cable stuck to your new X pipe.

ok a section of the cable is melted, i noticed it before though. when i had my clutch done, dude didnt fully secure the cable.

I guess i have to replace the whole cable correct?

Id say yes. I hear routing the cable is a pain in the ass.

routing the speedo cable is really easy, there's 1 metal clip on the frame rail on the drivers side that you attach it to, then just get it into the VSS on the trans and into the right hole on the firewall so you can hook it to your speedo.

pretty easy, but still a pain in the ass to have to pull the gauge cluster, I hate doing that.

ok I installed my new cable from 50resto and i still have the same problem. It went straightforward but was also a PITA.

Could the sensor that the cable plugs in be bad?

i hear you on removing the cluster...most of them are a B I T C H!!!!!to come out, Ford makes the wiring an exact length with no slack to give u much room to work with...GL!

CLuster took 5 mins tops to pull, now i replaced the cable but still have the saem problem?

Im thinking its the gear, or the sensor that could be bad. any else run into this problem?

Sensor has no effect on your speedo. One of four things are bad; speedo, speedo gear, trans internal speedo gear, cable. That's it.

Im going to check the gear that the sensor plugs into. ill ed up replacing it most likely. if it still doesnt work im going to swap out the cluster. thanks everyone for the help.

try the speedo gear. worth a shot and the next cheapest thing to do.

If you need to get a new gear, make sure it has the correct number of teeth and that the teeth run the same direction as the old one. Ford makes the with right and left handed teeth.

when you pull the cluster you can install brighter backlights! I put LED's in mine
