My wiring is proper bag of liquorice all-sorts which helps when tracing circuits.

Newer cars have all black wiring. For those that would like to tackle it but wonder how it is done, here are a couple of tips.

A couple of map pins with  a stranded wire tightly wound round and all but the last 5mm heatshrinked make good probes for the continuity buzzer on a meter Push one through the wire you have one end of and go poking and prodding the others until the other end is located.

It is a bit brutal but it works. I use it if I cannot get enough information

There's another way. You need to do some research and find both a set of circuit diagrams and a set of diagrams showing component locations.

The last part is to find the Ford connector pinouts. 

Given the connector number from the circuit diagram, a place to expect to find it from the component locations and which pin is which from the connector diagrams,  it becomes a simple matter of tracing pin to pin, plug to plug so it doesn't matter what colour the wire is.

That is how the pros do it.

Some pointers to information:

Cardiagn.

Is a useful source of manuals which will have the first two. 

2020 Motocraft pigtail .pdf should Google up a link to a document that identifies the connector if not the pinout.

 

Before my HGV driving time, but, Renault Magnum tractor units were the same.  Every wire was black, according to my gaffer, and there's usually a lot more wiring in a unit than a car.

It's, IMHO, all designed to stop independent garages and individuals fix stuff themselves.  Same as some new cars needing the front bumper removed to change a headlight bulb, and a host of other stuff that is a ballache to do. 

No. As cars become more electronic, more of the mechanic's skills devolve to the electronics engineer.  The tips above allow anybody brighter than a green salad  to find their way around the loom in the same way that the electronics engineer does. It ain't witchcraft, it is the twenty first century.

Negative.

Plenty of folk are "brighter than green salad", but, pin out's and wiring diagrams are beyond them.  Tracing wires when they know the colours of them isn't.

That's actually quite a condescending statement that you make.  It's an, "I'm better than you, bow before me." attitude.  Not big, certainly not clever.

You're obviously quite knowledgeable, you remind me of a former regular poster on Scoobynet, however I find your attitude a bit "off" at times towards others.  Each to their own though.

 

I don't think it condescending to expect people to understand simple explanations when given but those too blinkered or ignorant even to try to learn  serve no useful purpose in the discussion nor to themselves.

 

 I would have expected better but you'd accuse me of being condescending so you continue to declare it a conspiracy against skilled people  and I'll file you under lettuce instead.

Once again, you prove my original point.

I could be very petty, and advise you to use some of these more efficiently:   ,,,,,,......'''''''  ,but, I'll not.  Given that you are so much better than everyone at everything, I think it would be wasted key strokes.

Gladly file me under whatever you feel fits, I don't really give a *****. 🙂

But it would only serve to show that your command of written English is  embarrassing for a self perceived grammarian, particularly one whose attitude to those that might want to understand something currently alien to them  is as  patronising as it is so blissfully ignorant.

 You  are not interested in the subject and have made that clear from the outset. You are only here for conflict so shove off and leave this to those who may be interested.
