I didn't use their instructions for trimming the steering wheel cover. I had purchased the cover from the link in the original post. The stalk from the Rostra kit (the one I bought from thecruisecontrolstore.com) is OEM as well - very nice. I can send you a pic if you want, but it looks totally OEM. Yes, the dash light works as well. I was pretty discouraged after reading alot of posts saying that cruise most likely wasn't possible on these trucks, so I'm sure you can understand how stoked I was when I pushed that button and saw the light come on! Then took it for a spin and all worked!!!
Yes, the $35 is for the clutch switch and associated wiring. It's a good kit. The instructions are not the greatest for tearing apart the vehicle, but the pinout information was spot-on. The instructions I received said '09 at the top, but the pinouts were the same in my '10. Had a great trip to work this morning with my new cc!!!!
I'm happy to help any way I can - let me know if you have any questions.
(by the way, I'm a chick with no automotive electronics know-how, I'm just very determined and smart enough to carefully follow instructions when it comes to messing with my brand-new truck
