I have it in pdf but the file is too big to attach it.
If you look around there are some places to download the entire service manual for a 2006 Toyota runner.
In the audio section folder # 053004.pdf has the plug wiring information. I think it's what you are looking for.
If for some reason you don't find or get it. You can PM me an email address and I'll try to send that folder over.....My version of Adobe won't let me just save the couple of pages w/ the standard stereo system on it.
Anyone else have it? I tried to compress it and even zipped it's too big to attach here.
I found the download on toyota120 somewhere.
