2014 Fiesta S Cruise Control Retrofit 7 vs 9 wires

[Knackebrod]

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.

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.

- And thanks for that YT link! It will help a lot of others searching for that...

I just made an account to thank you two for coming up with a solution for other folks with 7 wires "problem". I've been searching for a pretty long time and this is the best solution I found, and maybe the only one out there. I drive a Fiesta 2010 MK7 EU and I will try to do this. I know the clock spring connector is not the same (mine only has one row with 9 pins) but i will try to come up with something and maybe if I remember to post it here so it can help.

Sorry to kind of hijack your thread...but I just purchased a 2012 Fiesta S sedan. I am a single mom and know nothing about wiring. I want to install cc on my base model Fiesta, it doesn't have anything on the steering wheel. Would it be advisable to just go to the junk yard and find a complete steering wheel with the entire setup included? I'm not that tech savvy when it comes to automotive stuff, but I CAN do some things What is Forscan? My car is a 5 speed manual transmission. I really like the car, it's just a little too bare for my liking!

I’ve been following this thread with interest. My car is a 2009 European Fiesta 1.6 TDCi, manual, base package and I’m looking into the cruise control retrofit as well.

A few questions I’m hoping someone can clarify:

• Has anyone managed to enable CC on the 7-wire setup without changing the whole clockspring?
• Do you actually need to add the two extra wires to make it work, or are there other hidden requirements?
• Are there any cases where you need extra sensors (like clutch/brake switches) or a different module (BCM/PCM) for it to function?

People on YouTube video you posted wrote that it is possible. But I would like to confirm that.

Would really appreciate if anyone with a similar setup has done the retrofit successfully and could share the exact steps or parts list.

Thanks!

So did you have to replace al the wiring or not, I also have only the 7 wires and have also been searching for a long time dor some good explanation

Remember that to know if your system will be able to even work, it requires that the wires and the steering wheels arm assemblies are wired and have the Proper pads and wiring already installed.

Now to simply say, go out to the junkyard and get a steering wheel that has these already there, you may have to drag half the drivers side steering wheel assembly and the dash board and instrument cluster pods back home with you in order to properly wire the unit up.

Then wire the assembly to fit the IPCC (Instrument Panel Control Cluster or Console) with the two wires needed. While the other part of that wiring harness you dragged back home with the steering wheel will also have to be installed and hope the harness it's plugging into has the proper supported wiring.

Ok, the issue of Cruise control from earlier model years gets greyer and greyer as time advances to this current technology.

You may not have the Electronics Support for this retro-fit to even work.

To help you know if you can even make this work is to go and place the Pods in a HEC Test mode and that will help you know if your vehicle will support the Cruise Control upgrade or not.
In the Fiestas with such a IPCC setup - the 3-rd button-press brings up this all lights test...


As discussed in a previous post in this thread, you will have to know if the Light and it's symbol for it is even present on the DASH panel. How? You use the HEC test mode to light up test all the lights on your Instrument Panel Cluster in both pods to find that symbol.

​

If you have the symbol in the "all light test" portion of the HEC, then it's highly possible you can install the Cruise Control - just be ready to shell out some $$$ to find a FORSCAN revision that will be backwards compatible to the year of your vehicle and be able to find the Address (in the Modules they use CAN BUS to address and call out). So each module is addressed by either a name or in the module - an actual hexadecimal address - not only for the programming to work, but as an means to ENABLE or NOT_ENABLE the function so the system can "tie itself" to it using the on-board programming and system calls it needs to have to make the PCM work autonomously with the IPCC and that specific area of programming to make the Cruise Control and Throttle work with the sensors it has and can see.

There are several keywords to this, the one I'm trying to point out - is "Sensors".

In a Fiesta the IPCC uses either the TCM (Transmission Control Module) and Brake, Downshift (Hill assist control - or Overdrive Off/Disable) switch on the shifter and those pads - to work the system.

IF you have a Manual - then the system doesn't know of a TCM, it only knows Clutch Operation - STARTER, Brake operations - so it needs a level of input from the sensors to work.

IF you have disabled a sensor or the system is too old to have one because it was not built to or for - the SIGMA engine or even it's earlier Ztec - you may not be able to even use Cruise Control as posted here in this thread - you'll have to find another way. Else re-install that position switch or Module and try again, or realize this type of integrated operation is not possible with your version of the Fiesta.
