Steering wheel harness for Android head unit

I highly doubt that you will be able to use any of the factory controls with the replacement stereo. The factory controls use the CAN network to control the OEM system while the replacement uses direct switching. That is why there is no adapter, because the two systems are not compatible. The unit you unplugged in the dash is not the actual stereo either. It is a display and control head only. The actual stereo system has three to five modules and is also connected to the instrument panel, the body control module and the traction control systems. That is why the various plugs you removed have so many connections. Anything that you control or view through the OEM head unit will be gone with the new stereo and you may have other issues depending on how the security system and options like remote start, key-less entry and such are connected into the system.

FYI there is no universal wiring color system for vehicles, so attempting to wire it in using blue to blue, red to red, brown to brown etc., will result in a lot of damage to the vehicle and the stereo. The attached wiring is for the basic system.

HI! I got the steering wheel control to work. Had to get diagram from the dealer and got the wiring to work. Thanks anyways!

Did you wire direct or find an adapter?

Wired it directly, sort of customized jumping harness. Its not easy though, and will not recommend it, unless they know what they are doing. Took me a lot of research on the wiring schematics of the Rav4 steering wheel control and got one from the dealer, Also I was fortunate to find an electrical auto parts seller that customize harness', so I did not need to splice on the stock wire.

Sort of what I expected, a cut & paste harness to connect the wheel switches. Those can be "fun" to do. I've done a lot of custom harness work like that over the years, but doing it myself and telling someone the process is a lot different. Especially with the newer vehicles, cutting into or splicing the wrong wire could do serious damage. One of the hard things on this site is judging the actual skill levels of the person asking the questions.
So I tend to "discourage" the questioner, just to prevent the "Well you told me to cut the blue wire and now the ECM is burnt up" replies.
Sorry if it made you think this site was a waste of time. Please return if you need other assistance.

Yup! We'll do! Good thing my steering wheel control was analog, that made a whole lot of difference. Thanks again!
