2014 Fiesta S Cruise Control Retrofit 7 vs 9 wires

I'm hoping to retrofit CC in my 2014 Fiesta S (North America).
There's good resources in other topics and youtube but I'm struggling finding more info on my case. All the examples seem to be for European Fiesta's and not sure if it works the same way for North American models.

According to the big WWW it can be done but you need to have the 9 wires going into the Clock Spring.
In my case I have 7 wires going into the Clock spring... For most people it would end here.
But I'm trying to figure out if I can still make it work.

The two missing wires go from the Clock Spring to the Instrument Cluster (pins 27 and 28).

If I add these two wires, will I be able to get my Cruise Control to work? Or am I missing more parts? Swap BCM as well?

Hoping to find someone who has ventured this way and can help me out. But I am tempted to give it a go.

Picture from my Clock Spring connector.

IN regards to the Clockspring - being that you have the main connector - the USA versions of this use a type of "padded" control button...



You only need 4 wires - two reserved for the lighting.

The other two which you seem to be talking about - the SOCKET side (the upper row of numbers) use 8 and 9 and the PIN side - the Lower row of numbers - 9 and 10 - but do you have the correct pad?

The Padded part is what is interesting - because it uses a set of dropping resistors that send a control voltage level per press - as the signal to tell the system what to do.

Including a High logic level to turn it off - but to turn it on, then requires a low-logic level above 0V but well below the Control RES signal - so it looks for a level of impedance that changes between the CONTROL RES and CONTROL RTN. When its at rest it's still active - but idle until you press a button - for all the resistors "sum" to a known low-value reference level - it's self zeroing - but when you turn it on (On button press) that raises the signal level and tells the Tell-tale light to turn on - the rest goes from there.

Now you ask if your "S" version will work, on mine it did, but it came standard. So I can't tell you with 100% certainty it's going to work. To know that requires you to Turn the key (press the button) to ON but not start and look for that symbol ...

IF the symbol lites up on that cluster somewhere, then it is possible that the Instrument panel system can take in the hookup and will work - for if it is on the panel - it might just need the two pins on the Instrument panel harness side to be connected - no guarantees though - this may need a "Forscan" moment.

Thanks Andy for the very detailed answer!!
A few more details about my car first:
It is the most basic version, manual windows, no A/C, no key fob, basic radio, no audio control on the steering wheel. As boring as it can be!
When I turn the ignition on it doesn't show the cruise control symbol as you described.

I decided to give it a try anyway! Went to the local pick n pull and picked up a steering wheel from a 2015 Fiesta SE automatic (it has audio controls and cruise control on it). My car is a manual by the way.
Also I took the wiring/connectors from the steering column and instrument cluster just in case I'd need them or to compare.

Removal/installation of the wheel is very easy.
Disconnect battery, pop of airbag by inserting a "pin" into the holes on the sides and bottom of the steering wheel (3x, doesn't have to be simultaneously), disconnect three connectors on the airbag, one bigger white connector that connects the steering wheel to the clock spring, loosen the 24mm bolt (socket required, it sits in), remove steering wheel.
Installation reverse.

Download forscan, get the 2 month free subscription, connect to the car with a $20 amazon obd 2 plug (look for a forscan one!), open forscan, backup the car data before making changes! Go to the cruise control setting and switch to 'with cruise control', go to audio control on steering wheel and switch that on as well. There's good videos on YouTube.

That's it, you now have cruise control! Works like a charm for me. After the software changes the green CC button pops up as well.
One note though, when I hit the "on" button for CC on my wheel nothing shows up on the dash.
But when I hit "set" after, the green symbol lights up and CC is set. Not sure if this is normal. Just make sure when you go test you hit the "on" button once or CC won't come on.


Audio control buttons work as well except the voice control because my car doesn't have that.

Yes, you don't know it's on until it's "SET" or "RES" - then the lights on. And it's engaged. So when you go back into the HEC mode, you'll see that Lights test will wink that CC light.
