I am attempting to replace my stock radio in my 2005 RX330 non-Nav non-ML system. I've replaced systems before and always looked for the color code online. I've hooked up what I was able to identify and the system turns on and functions, but I can't figure out my speaker wires. They do not match what people are saying online.

Below are the wires remaining and I just need to know what are the speaker +/- and what is the steering wheel controls. I am short of just toning them out with my network toner.....

I'm confused as to why you would cut a stock harness and not buy a $15 adapter?? I have used a 9v battery to find speakers before. You touch the wires and you will hear the noise in a speaker when you get the wires right. that method would be a lot easier then toning with network tools..

i have the same problem and cant find a wiring diagram anywhere. did u figure out the colors yet?

you should also remove all of those crimp connectors and solder each and every connection. matter of time before one lets go and you have to tear into that dash again.

and i agree with the above. get yourself an adaptor. even if its 40 bucks it would be worth it

This has everything you will need. $15 for two days of access, but totally worth it.
