That's right. For all you guys who want to install it, first take a small straight blade screwdriver and pry the blank out of the dash. Pry from the bottom not the sides. It will come right out. The harness plug should be plugged right in the back of the blank, of course it's not plugged into anything electrical. If you don't have the small harness plug with about four wires going to it, forget about the retrofit. If you do have the harness plug, you're in business. Go to the Ford dealer and have them contact The Cluster Center and order you a new 6 gauge cluster. Have your mileage, & vin# handy. They will need it. The Cluster Center will program your mileage into the new cluster which I'm sure will be a bit off once it's installed. DO NOT INSTALL THE CLUSTER. You will have to get a Ford tech to use their WDS computer to first pull the info from the old cluster, then install the new cluster with the info that was taken from the old one. It only takes about ten minutes to swap clusters. This is all I know so far. I'll find out more soon and keep you guys posted.
By the way, most guys are spending $500-$600 total to have this done. I wouldn't even do it if I didn't score a used cluster with similar mileage on it. If you do get lucky enough to find a used cluster make sure it's for your model car. For example, a GT cluster will not work in a V-6 car. The tach supposedly will be inaccurate. That's what I read on another forum which they won't let me link to according to stangnet rules.
