The gauge cluster in my 2003 WRX is looking a little rough, and I came across a 2006 WRX gauge cluster for a really good price. I have ProSport gauges in my car now, and they're green, so I kind of want to stick with the green theme. I was wondering if this would be a plug and play thing, or would it be really difficult or even impossible? And how would I be able to get the outside temperature to work? If someone could help me out, I would really appreciate it. Thanks!
