I sure do. I'll PM you the details.

I'm working on installing the 2-button cruise control on my 2012 L automatic. I am having trouble identifying the correct wires to connect to. On the 06-11 D3 plug there is a black wire, and then a blue and brown wire if you have the correct wiring to the computer. Here's a pic I took from under my steering column. If I were to assume, I'd say it's still the brown and blue wires on the plug next to the yellow one. But I'd rather double check with you guys who know.

Link to the type of cruise control mod I'm using.

For the 2012, the CCS wire (formerly blue) is now beige and the ground wire (formerly brown) is still brown. They are the two left most wires on the black connector to the left of the yellow airbag connector.

Awesome, thank you very much. I never would have guessed it to be the black plug.

Well, I tried to hook this up with no result. I'm partially color blind so maybe I could have the wrong wires. Is there a diagram of the black plugs pins somewhere? Is there a black wire, or a dark brown?

This is the connector drawing (view is looking into the holes where the connector would plug into the clockspring). Pin 1 (beige) is the CCS pin, which goes to the ECM. Pin 2 (Brown) is the ground wire.

Thanks for the quick response, and expert electrical knowledge. I used a micro pot instead of resistors. That shouldn't be a problem should it?

The problem with potentiometers is that depending on the construction they can drift. Also, depending on the range of the pot, the under 1K area of the pot can be very small, making it difficult to lock in the correct values.

Just wanted to let everyone know I got it working and it's great. I probably ran into every problem that one might run into, but with quick help from CTScott I was put back on the right track. Thanks again Scott, and the forum as a whole.

Got the cruise stalk in my 2012 3dr., but does anyone know where there is a tutorial to get at the clutch switch?

The clutch switch on the 2012 is just like the 2nd gen. Look at the top of the clutch pedal and you will see a bolt threaded into the frame, with a stop nut where it meets the frame. Remove that bolt and install the CC clutch switch in its place. The switch should be adjusted to where it is fully pressed in when the clutch pedal is not depressed and, where as soon as you touch the pedal the switch is no longer pressed.

Hi Danieldk,

Have a look at post 37. I have the paddles and had the same issue with getting to the 2 clips at the top of the wheel.

What you have to do is use the hole to push the bottom clip which should release part of the airbag. There are no other holes to get to the other clips so you have to get to them through the gap you create when you release the first clip.

The major thing you have to notice is that the bottom clip (the one you get to through the hole) needs you to push the clip to release it, the other 2 need you to pull. I used a small ring-ended spanner to pull the other clips and release them.

Let me have a go in paint and try and illustrate what you need to do:

Step 1 - push the first pin through the hole with a flat screwdriver. It's the yellow arrow.

Step 2+3 - pull the far away end of the second and third clip towards you. These are circled red in the diagram (sorry about the cables being in the way on the photo of the lower clip but it's just the same as the upper one)

This makes me wonder if the Rostra CC install is the same for the 2012/13 as it is in the second gen. I yanked it all out of my 08 to put in the new one, just haven't gotten around to finding install guides for it, lol

Did you have the Rostra with the little stalk on the left side of the wheel, or the Rostra kit which used the OEM right side stalk?

[mr_miles]

i have the kit with the stalk on the left side.

Ah. That will probably still work, but really isn't worth the effort. With the 2012, you can simply install the OEM stalk and be good to go (without all of the crazy wiring required for the Rostra kit). If you are interested, I would trade you one of the OEM stalk kits for your Rostra kit, so I can experiment with it to see if it would really work for 2nd gen European owners (I have suspected for quite some time that it will, but have not had the opportunity to verify).
