I want to get some 2005 xb RS 2 side view mirrors and put them on my 2006 RS 3 , have them repainted of course, is all the wiring in place for the turn signals or would I have to get that too??

 

They are actually covers on top of stock mirrors (3m tape), and you will need to run the wiring.
You can find aftermarket ones on e-bay and Yahoo Japan Auctions, there are also Toyota OE parts available here but they are expensive. Keep an eye out in classifieds and craigslist. good luck

E-bay ones will probably require some work for fitment

Try to look up the mirrors on ebay and see if there is a junkyard parting an rs

 

Wow, so they are just covers :\ I will have to take a closer look at them the next time I see a yellow RS. Yeah I looked up on Car-parts.com and found a left yellow side mirror I am sure I can find the right but its its just a cover not sure its worth it. Should try to find one more local and pull it myself with the wiring...
