Of course you are still going to need another MDC control box to run all of your gauges, etc. but whatever you do don't pay a dealer $125 labor to replace it. It is a piece of cake to replace yourself. I would recommend saving up and installing Perfect Pass. It is also a relatively simple install and you will never regret it. We call it "the marriage saver".
