Hey all, I just got a 2000 Focus SE with a manual tranny. I want to swap out my tach-less instrument cluster for one with a tach. What I want to know is, will the new cluster correctly display the odometer reading and/or throw a trouble code? I have about 25k miles on my car now, and if I get a new cluster, will the new cluster display my mileage or the mileage from the car the cluster is pulled from? Also, I saw a listing of the different DTC codes that can be viewed on the cluster at focus hacks. Code A139 is "PCM ID does not match between Instrument Cluster and PCM." Is this something I should worry about? Would the swap cause this code to be thrown, and what could I do about it? The reason I'm concerned is because we got a dealer warranty with the car, and I don't want it voided from this. Thanks in advance for any information.
