Stealership? Might have to get the entire steering wheel! $$$$$

 

I am not all that familiar with the newer 4Runners, but I did a little search. Take what you see below with a grain of salt, as my experience with a 2015 4Runner is limited to seeing them at the Portland International Auto show for new cars......

Here is the only diagram I found with that assembly:

It appears that the Part Number Code: 84250A is what you are looking for, which, unfortunately, looks like the entire switch assembly for both sides of the steering wheel, which means it will be expensive!

SWITCH ASSEMBLY, STEERING PAD
Part Number: 84250-35080-B0

Toyota's MSRP price is $498.82.

Hopefully I am wrong and the plastic trim is available separately, but this is all I could find.

I do not know of any aftermarket versions yet.

You might be able to get a used steering wheel or possibly the switch assembly through eBay or through http://www.car-part.com/ ( multi- salvage yard search) for significantly less than a new assembly.

I am not sure how much the air bag gets in the way of this assembly either.
