First DIY on my car, installed CC stalk from Alfa 147. Bought this CC stalk few months back from ebay UK, it was shipped and delivered in 15 days. Rest of the stuff was from Aliexpress/local stores. ECU connector pins from rsdelivers website. You can find all links on Wildy's
post (DIY: Cruise Control installation on my Fiat Abarth Urban Cross Avventura) on the same. His thread was really helpful. Also referred to Rajan sirs thread
here (DIY: Cruise Control for the Fiat Linea).
You will need following.
1. Ebay UK - Alfa 147 CC stalk
2. Aliexpress - 4 pin connector - i have used two pairs of them, you might need more/less depending upon how you do the wiring.
3. Aliexpress - 1 pin connector - I have used 2 pairs of them, again you might need more/less depending upon the wiring.
RSDelivers - EQS Pin for ECU - You will need 4 pins.
3. PVC wire 22-24AWG - 3 meters x 5, if you can get in 5 different colors it would be helpful in wiring.
I had ordered wires also from Aliexpress but it was silicon one and too soft. Later bought some PVC wires from nearby electronics store along with below stuff.
4. Rubber sleeve - 3 meters
5. Corrugated pipe - 3 meters
6. Automotive tape
I have covered all the wires with rubber sleeve then wrapped with tape, for engine bay wire i have added corrugate pipe on top and wrapped with some more tape.

I will add some pics of the installation. The installation is covered in complete detail in the thread links i have posted above.
Ready for mounting, this is small plastic panel from steering wheel shroud where CC stall will be installed.
Removed the mount from the CC, this can not used on Punto stalk column.

This is how it looks after mounting the stalk.

Interior wiring, this cable was used to connect the cable from ECU to CC stalk and fuse tap to CC stalk.
Connectors on the steering column, this is where CC stalk was plugged in.
Engine bay wiring, i didnt took much pics of this work, as i struggled a lot with the ECU pins and moving the wiring through firewall.

Wiring
Installing the ECU pins was difficult because the wire i had used was very soft and i was not able to push them in, they are seated properly and i can't pull them out but the secondary lock is not sliding inside(purple tab in below image) Need to figure this out.
i have routed the wire from engine bay to interior through the firewall. There is a hole for bonnet release wire, as its small hole with rubber gasket it was really tough to pass these 4 wires with sleeve installed. As the hole is further below the wiper mount, even access to that place is limited, you can just feel the rubber gasket with your fingers. Somehow with a lot of effort i managed to fit a metal wire in that hole and then tie the wires in that metal wire and pull from other side.
Now only thing left was to enable CC in ECU, body module and dashboard module. That was another challenge, will explain in next post.
