Technical Fiat ducato 2014 motorhome wiring help

[PWLambert]

I have an Adria Sunliving on a fiat ducato base 2914
The horn stopped working so used the forum to help
Checked all common problems-
fuse good
relay T03 works
horn itself works
Removed steering wheel and checked connectors etc one has earth fine other wire does not have continuity to relay
If I bypass it from relay to circular wire on horn pad then press spring connector horn works thus diagnosed broken wire
Removed unit under steering wheel tested this ok
Got to black wire in steering column loom and connector under fuse box under bonnet
No continuity
Took off dash panel around steering and loom seems to go straight down column into main loom then through firewall to engine bay
Does anyone know or have a full wiring diagram to show and other loom connector I have missed that may be corroded etc before I start cutting and patching into my loom to bypass this
Sorry so long winded
Thanks in advance

No D001[A] in x244 eLearn. (On the x244 there is also a D001. All intermediate connectors have the format Dxxx. On the x244 D001[A] is a 20 way connector with an 8 + 12 + 12 + 8 format.
D001[A] is typically towards the LHS of the dashboard.

OK, get that now. The diagram I've reffered to is still incorrect, as it has several pins and the D001 in the x250 / x290 is only single pin.

eLearn wiring diagrams do not indicate the number of pins on a connector. They only show the relevant pin(s). If you want to know more about a particular connector, you need to scroll down from the diagram, and click on one of the sometimes bewildering choice of links for that connector.

Other shortcomings include the failure to indicate a common point, when other items are supplied from the same fuse.

That in fact ruined my life.

Of course it's obvious and logical, but I just thought the easier way to track several things I need to track in my car. Or I played too much with the door loom lately, which consists of several different connectors on the receivers' end...
