Update: change some words & correct wiring colour.

Look at the fuse box near the battery under fuse there is 4 wiring plug. If your don't have then you need to wiring up from ECU pin number 41, 58, 8 and 9 (SEE WIRING DIAGRAM)

1) Check the fuse number F1 70amps is insert and go interior look at the fuse number F37 10amps, F42 7.5amps, F49 7.5amps and F53 10 amps if your is not there insert it.
The clutch sensor make sure it have them or otherwise if brake sensor fail it can't be switch off the cruise control, that is why have extra safety to deactivate it on clutch when press. You can buy sensor from eBay £6

2) My Alfa 147 cruise control stalk from scrapyard £14.99 with 5 pins (5 wiring) remove undercover from steering wheel, the cruise stalk arm holder remove the second hole (see picture) with file till the hole disappear otherwise it won't fit, tight it up with one screw.

3) Drill a 7mm hole under near the heated blow fan motor on the passenger side, buy 4 of 3 meters wiring max up to 15amps. If it is greater than 15amps it will be too thick to put through the hole! Put wire out from interior is more easy.

4) Cut the plug off on fuse box at engine bay. Tight it up 4 wires with 4 pearl terminal blocks, and connect it to your wiring from the interior (to make sure to put up label and write the colour name at end of wire or follow by multimeter resistance switch to 200)

5) Cut off the cruise stalk plug and fit same 5 pearl terminal blocks

the colour wiring match is:

Switch on/off: yellow to the ignition wire with 7.5amps fuse

Resume button: green with green/yellow

Signal to ECU: orange with light blue

- decrease speed: dark green (some have black or navy) with red/yellow

+increase speed: red with red/grey

6) On HGT and Eleganza already have setting from ECU which is not required to relearn, you can see cruise light icon on speedometer when you switch it on. update 1.3 multijet Dynamic it will work

(But I am not sure about the Sporting and Active it mind need to use Multiecuscan and relearn it) update it will work on Dynamic without relearn

Test drive to make sure the cruise go off when touch the brake, clutch some other Fiat it will go off when apply the handbrake and pull out of gear.
Try to use the increase and decrease speed knob and the resume button,
if everything is works fine then tape up all the connect to protection from damp/wet and short circuit then refit the undercover.

Good luck!

Still have not a clue why it not work but I will post here again:

Βritish English appears to have taken a notable turn for the worse since I was at school.

I can understand what you say, barely, and you appear to know what you are talking about but your English makes my head spin.

I always used to say to US colleagues that if they ever find themselves in London they will be lucky to understand half of what the people say half of the time and they didn't believe me.

There you go.
 
Any idea where that plug goes to? is it one of the large plugs under the fuse box?

also, anyone have the pinout for the connectors on the bottom? I've had a scout about online but can't find anything
 
Ciao a tutti,scusate se scrivo in italiano,ma mi servirebbe una mano.. qualcuno è riuscito a farlo funzionare nella 1.3 mjt dynamic? Che pin ha utilizzato nella ecu?
 
:bang::bang:
Update: found the plug under the engine fuse box, colour wire is match to the diagram but in wrong order. Later try fit temporary wire from the plug to the cruise stalk plug see what happen, but one more wiring colour is Red/Blue still have not got a clue what is the picture in diagram number D097? is that relay or resistance?
hi! how can i take the pin out from ecu ? i don't have access to the wires to put the pins.
