Thanks Mik1! Alot to dig through and exactly what I wanted. Please be patient with me if even after reading through I have a few more questions but this is definitely just what I was looking for. Thanks!
Not trying to thread jack or anything however this is one of the two things I wanted to get added. From what I can tell from the previous posts, there isn't a rear harness and we need a reverse maleadapter correct? I haven't opened anything up yet, mainly building a parts list so to speak. Wolfelimninator could you confirm if this adaptor would work? Or better yet, where you found yours at? Amazon.com: Reverse Wiring Harness for 1984-2007 Toyota Lexus Scion Vehicles OEM Radio (71-1761): Car Electronics I know it says lexus and the colors are off but if I'm adding new wire shouldn't matter too much as long as it plugs in. You mentioned something about quality being a problem for the rear speakers (amp could be added) as well as things in the way for the rear wires to be run? Oh one other thing, what ever happened with the dimmer line was there anyway around it? Just avoiding cutting wires don't want to screw up the warranty, if its all plug in I can reverse it if I have too.. Thanks!
