    Hey all, been lurking here for years as my 2006 Prius has been purring along wonderfully. A few months ago, a guy on a motorcycle slammed into my left rear door. I wanted to replace it with a salvaged door and I found one in great shape with the same color (blue).

    However...I get it home and start to assess what's needed to remove/replace it and to my dread I realized that my maxed out car with the JBL sound system has a rear speaker in the door panel by the door handle. The one I got doesn't have it. Crap.

    The place I bought it from is willing to take it back if it won't work, but before I did I wanted to ask the brains here if I could swap the door panels. I'm guessing that the wiring harness might be different, but I don't know for sure. I'm hoping that Toyota built them all with the same wiring harness for simplicity. I'm not looking forward to transferring the harness from the old door to the new--or if it's even possible given that they're not the same package.

    Can anyone advise me on the chances that I can still use this door? Thanks.

    You should be able to move the whole wiring harness from the door you have to the door you bought which will have all ya need pretty quick to do. You should be good should be plenty of videos of people moving door harness similar on most Asian cars

    Thanks for the response. After searching until my fingers bled, I realized that I should just call a dealer to get an answer about the harness. Turns out that the wiring harness is different for the 9 speaker JBL system that my trim package 8 has. The dealer supplied me with the part number (5215447070). For the 2006 (and perhaps later models) there were two wiring harnesses for the back door--my trim package and every other package. Just FYI, the other harness number is the same except the last two numbers are "60" instead of "70".

    I popped off the inner door shell and found out a couple of things. First, the harness part number is correct. Second, I finally found out the noise that had been coming from that door (even before the accident) was from the two blocks of rigid foam had broken loose from the inside door shell and were rattling around inside. Ugh, that was so bloody frustrating. Now I can take some hot glue and re-adhere them to keep them from moving. I also realized that the second speaker in the door shell (by the door handle) doesn't have or require a cut out in the metal of the door shell to accommodate it, so the new door shell can be used with no problems.

    Yes all that . The JBL w GPS and disc changer and tweets on door use additional wiring . Usually just pull door harness on you're original damaged door put it in new door you gonna use generally can't go wrong but.
