If you get the MyColor instrument cluster, it runs $400-$600 from ford. Then you need other wiring harnesses to run it to the rest of the MyColor hardware in the car. Such as the Premium door panels, footwells, door sills, and cup holder.
I am doing the conversion myself except I am going full Premium. Its not so much because of the money, but because I am learning alot in the process.
I have replaced my cloth seats with leather ones from a premium - $1,000.
GT500 pedals - $50
Leather e-brake - $50
Interior Door Panels from a Premium - $600
Shaker radio bezel - $70
Aluminum dash trim - $400
Lighted door sills - $180
Footwell lights - $10
Mycolor cup holder - $80
Last things i need to do is the Premium Instrument Cluster and Sound system. Will probably opt for a better one then the stock. Now i wont have the Ambient lighting that changes colors, but Blue is good enough for me.
If you know the part numbers, you can check fords website for everything. However, i bought off ebay. The door panels were extremely hard to find. I installed everything myself. Here is a pic of mine, door panels will be here later this week as well as the footwell lights.
