I have a 2000 Tahoe with 95000 miles, the odometer display often will not display when the truck is turned on, also the speedo needle is clunky. I was wondering if I can do an entire cluster swap, plug in another one and go, or does the computer need to be reset and will the odometer read the correct mileage. I am interested in installing a cluster from a escalade of the same year to make things a little better looking. Thanks let me know. Also does the cluster need to be new or refurbished or will a junk yard model do the trick?
