The switches were of the same kind as the one I ordered earlier through the dealership. They were silver color, but had a honeycomb texture. Next thing I did was without removing the existing blank insert, I plugged in the new switches and extension cable to see if it works. Fortunately it did! See below:

Next step was to remove the existing blank plastic, and this is where things got frustrating. The proper way to do this is to first remove the steering wheel off the column completely in order to access the two screws to remove the blank. Unfortunately, a special tool made especially for removing steering wheels is needed to do this, and of course I don't have it. I tried trying to yank it off by removing the large nut in the center of the wheel, but damn the thing is solid. It was getting late at night and I was getting impatient to go hunting for another tool, so I went to plan B. This involved putting a phillips bit into a the small opening through the front of the wheel and very very very slowly removing the two screws. I used a needle-nose pliers to get enough torque to unscrew those screws:

The whole process was very long and frustrating as the gap was very small and the screw was very tightly held. It took me well over two hours and cut fingers to get those two damn screws off. Those metal are sharp, be careful! Anywho, the final result was this, getting that blank piece off:

Update! Here is that tool to remove the steering wheel. This is the specific one for Hyundai/Kia. I don't know if you can rent it, but if you can, that would be great.



And here is quick instructions on how to proceed:

Next I removed the existing extension cable for the cruise control, and installed the new y-splitter extension cable. Note: the cruise control side is missing one cable, the yellow one. Without this, the cruise control light wouldn't even turn on. Simple fix was I ran a cable from pin #3 of the MM01 connector to pin #8 on the M60 connector.

And here is the final result!

Overall, it was a good project. If someone else is planning on doing this, do yourself a favor and definitely get the tool to remove the steering wheel. I spent at least 3 hours total just trying to remove and insert those switches. Overall difficulty 10/10 the way I did it. Otherwise with the proper tool, I'd say 6/10. - kish21
