Are Harrier and Lexus steering wheels interchangeable?

I was thinking of getting an eBay steering wheel with the button controls, should be easy enough for my car audio guy to make them work given that I have an aftermarket stereo. Just not sure if the wheels are interchangeable though, anyone know?

Ok so an eBay seller told me that the wheel will fit, but I'm not sure if the car has the wiring in it for the controls to work. Is there any way I can find out other than taking the wheel off and looking for a connector?

Pretty sure there won't be any connector or loom present for functions not fitted at the factory..

Yeah that was my guess too, my car audio guy said a lot of cars are pre-wired though. I guess it might depend on whether there was an original option for the controls to be there, if so they might put the wiring into all of them just to make the assembly simpler.

It does look like there was a factory option that had steering wheel buttons:

I think Lexus are the same as most manufacturers, not including redundant looms.
