These are run by a module on your trans now. It is the same one that shifts the truck. They are kind of expencive to replace. You will see it on the driverside of you truck on the side of the trans. There is going to be two that you will see it is going to be the inside one that runs the speedo.

Did the transmission you put in have the the pick up on the output shaft. Pull out the vss and see if the pick-up is on the shaft or a speedo gear is on the shaft. If it has a gear, you will have to change it to a pick up wheel. The older 700 transmissions used gears.

I would recommend a used instrument cluster if you know of any junkyards around your area. Otherwise check Ebay or elsewhere on line for one.
