Question about steering wheel controls for post-facelift 4th gens

[2003V8LTD]

We have fallen in love with our '03 V8 and I ran across a really sweet '09 V6 Limited so I bought it. Am installing a double-din aftermarket stereo and hands-free unit. No particular issues there, except that I am totally confused about what part to use for the RHS steering wheel controls. On the 2003, I ordered:

84244-35030-B0 Switch, Steering Pad, Right
84204-58010 Cruise Control Cable

My understanding is that the Steering Pad Switch is the same part # for the 2009, but there is a different cable that’s used to connect it ... 58010 seems to not be correct for the vehicle according to various Toyota parts websites.

Anyone know?

Not sure if this is what you're asking, but I used the Crux SWRTY-61S Wiring Interface in my '07. Full stereo install post is linked in my sig if anything else there might be helpful. Tip: buy it from Crutchfield and you get lifetime tech support. Might cost a bit more up front but it's worth it to always have them a phone call away.
