Duato X244 cruise control retrofit- VICTORY!

Well, after 3 days of on/off toil, much aggravation, bad language and more- we are done fitting the Alfa 147 cruise control stalk; and it works perfectly!

The main thing to do is check for the wires from the ECU that come to the black connector D018A (the much talked about black connector) under the left side parcel shelf/dash (on a RHD vehicle). There should be 6 wires into it from the engine bay, a thick red and 5 thin ones. IIRC (but see pic) one is pink/green, and I can't remember the others (loads of info online and here) and I have a diagram IIRC but the yellow/black, one is not one of them, leave that alone, nor is the thick red one. I believe that will only be there if the vehicle has aircon.

4 of the 5 cruise stalk wires excluding the yellow connect into the 4 on D018A as seen in my pic- this is just to illustrate the connections, connecting themas per the Italian diagram below- watch the mating of one colour toanother as they do NOt match, I pushed the stalk wires into the black connector to see how well they fit/could they be reused? Short answer, they fit Ok but are hard to put in place so I had a plan B. Then you will need the wires extended across to the the steering column, whether left or right. I used spare 7 core trailer wire as I had some, if 13 core trailer wire is used, so much the better as it contains an orange one that is not in the 7 core and you can match stalk wire colours 100%. I had to sub the brown for the orange, and not forget I had done so.

I chopped the thin wires where they entered the black connector and used an ex PC 4 way Molex connector as the pins were easy to extract with the correct tools and it will handle the current OK. This was soldered to the thin wires, extending them a little to make more slack to work with. Things are tight!

From the output of the Molex, the 4 wires via the 7 core were passed under and behind the heater controls/map bin, above the pedals- beware steering column rotation and secure well from pedal interference! Then up to top of column, with lower cover removed.

I originally cut the pins off the stalk wires after removing from the plug, but ended soldering them back on. I had some terminal connectors from a superseal type 6 way plug and socket, the female terminals fit the Alfa pins 100%. I believe the are Delphi GT150 female and are available to buy seperately. After soldering them onto the relevant connectors on my 7 way, I covered them with heatshrink and could then plug them onto the Alfs pins on the stalk wires, which I had meanwhile placed back in its original plug. Note that the yellow is not connected to anything at this stage.

We then need an ignition switched 12v supply for the yellow stalk cable. This is taken from the blue/green wire to the brake light switch, via pin 3 of the brake switch (blue wire) then on to join the yellow stalk switch by whatever means/routes connection method you choose. You will also need a 4 pin brake light switch- this is a cow to remove (see my other post) and you may find your brake switch already has 4 wires into it like mine had, but this does not mean the switch has 4 terminasl in it!

Fortunately between my brake switch and the main loom, there was a 6 inch piece with connectors each end which could be taken out-with difficulty!!- and worked on comfortably while soldering on the wire to bridge pin 4 and 3, and make the extension to the yellow stalk control rather than try it at the actual switch terminals.

This yellow wire from brake switch 4 via pin 3 goes ultimately to the yellow wire on the cruise stalk giving such a 12v feed. the remaining 2 brake switch wires- pins 1 and 3 are normally closed with brake off, and provide a signal path to the ECU when cruise is engaged, that the brake is OFF and can engage. Pressing the brake pedal signals cruise to temporarily disable. BTW, when replacing brake light switch for a 4 pin one, make sure the switch body is the correct length, and vitally that the operating tit is the same length as the old one, comparing both when off the vehicle.

These bad access hurdles surpassed, and connections made and new brake switch in and working, it remains to mount the Alfa stalk and it will be self explanatory after looking at the parts. Some trimming of the stalk
may be needed where a mounting hole we can't ue may need cutting off.

Very carefully check and recheck all the connections are correct- I had 2 wires in the Molex at the black connector end reversed, easy to rectify. Make sure there are no shorts (you did disconnect the battery didn't you?) and try it out.

The green dash light did not come on immediately on mine and others reprt the same. It took about 15 minutes with random switch ons and offs. as I had multiecuscan, I had connected to the systems with this on first key on, as there is a force relearn facility for after doing just this mod. I did not need to do that, and all parameters and indications logged as operating correctly first time, and responded correctly to control inputs.
Icould do tis joba agin in less time, but would not relish it. It's done now, and a road test proved all was most satisfactory in all aspects. RESULT!

Re: Duato X244 cruise control retrofit- VICTORY!

I have beeen thinking about this install, and comparing it to the one in my Grand Espace. That has the same buttons to control it and the on/off switch too of course. However, on that it also has an extra button, that when operated, will temporarily disable (pause) the cruise until 'resume' is pressed. I find it really handy if, say the traffic thickens up for a while, or I find some other short delay or catching up to traffic, or the general flow is a bit up and down speed wise. This pause has the same effect as touching the brake pedal. So, on the Ducato install, as I don't have this pause facility and either need to brake slightly or switch it off completely then re-start and set speed again, I am thinking I shall put a switch in to allow pausing it. I reckon that if I put a push button switch- NC contacts- in series with brake light switch pin 1 and wherever it goes to, this will add the function by replicating a brake application and allow 'resuming' after pressing it and not having to start from scratch again. It will not affect the brake lights as they are on pins 2 and 4, and if I attach it before switch pin 3, it will cut the power to the cruise and it will need starting /turning on and setting again. It will be a while before I get round to it, but does anyone see any problems with the plan? Apart from yet more wires and the trials of getting them in neatly.

Re: Duato X244 cruise control retrofit- VICTORY!

Ocwobio,

I understand your idea. However as you suggest the implementation could be rather fiddly. If you decide to proceed, I recommend confining the alterations to pins 3 & 4 of the brake pedal switch. You would have to cut the loop that you have made between pins 3 & 4, connect pin 4 directly to the yellow wire of the Alfa stalk, and loop to one side of your new push button. The other side of the button would have to be wired back to pin 3 of the brake pedal switch.

The main problems that I can envisage, are push button location and aesthetics. On you espace you currently have a dedicated button associated with the cruise controls, and importantly easy to locate and access. This would not be easy to replicate with the Alpha stalk.

A separate button could perhaps be mounted on the dash or steering column cover, but it would have to be in an easily accessible location, otherwise you could be pressing the brake pedal instead.


Sourcing a visually acceptable, normally closed push button, could be problematical.

Re: Duato X244 cruise control retrofit- VICTORY!

Yep, aesthetics is a factor for sure. It will be a while before the trauma from the install fades enough anyway! BTW, the cruise switch on my Espace is in a horrible position, it was bad enough in my 05, down near the start button, but now on the later ones they've moved it to down under the parking brake handle, below my right knee, with 2 other switches, no chance of finding and switching it by feel, that's for sure. Maybe I ought to be moving that one instead.... I am going to get a new brake switch connector sub-loom length, and make hopefully a neat and tidy job whilst on the bench. The current one looks untidy, but does work well. Cheers for the input, as ever.

Re: Duato X244 cruise control retrofit- VICTORY!

Eh, I'm used to being forgotten about! In retrospect, if the black plug has the wires from the ECU, it's really quite simple, now I know how. And it works as it should, too. Glad I took the plunge. Now all that remains is to trim the lower column shroud to fit and put it back on. I have yet another mod I've thought out, relatively easy, when I can be bothered! Thanx for all your help in this mate. Cheers!
