Reassembly is the reverse. Insert the Speedo cable by first rotating the plastic retention clip back into place and "CLICK" it onto the new cluster. Very easy and an audible click signifies success. you might have to rotate it a wee bit on insertion to line up the square drives. Reconnect the 3 wire clips (2 white 1 blue) whites on the outside blue center right.
Before going any Further Put your key in and MAKE SURE ALL THE BULBS WORK you might even want to pop the column nuts hand tight just to take a spin real quick to make sure all works.
Slide it into palce wiggle and shove as needed gently till its seated. Reinstall the metal plate and 2 screws and then the White Tab Screws. How reconnect the plug for the defroster button and shove it back through the hole from which it came. reinstalling the dash bezel as you do. Reinstall the 4 screws for the bezel.
Set the Steering column top plastic in place shove the colum up and reinstall the bolts using your hands and then the 12mm socket to tighten. Install the bottom plastic using the 5 screws the machine screws go into the inside two holes the coarse scerws go into the other three. The pair of coarse screws secure the two plastic halves together so you may have to push them into alignment to seat the screws.
Reattach bottom dash plastic and your all done. Reattach the Speedo cable under the hood if you have not done so and have at it. Why did I make this swap? well more gauge is always fun but what I was really after was the TRIP METER which my cluster lacked. Now i have it.
I did note my speed is no longer accurate. Previously it was as close to exact as I could measure (within a fraction of a second) now its 4-5 miles per hour off. I am guess it came from a car with a different tranny maybe? no idea. Will have to figure out how to fix that.
