Checking the wires to the switch I found the white one had power, also the pink.
Seeing as I cannot find a way (even using Edge) to get a diagram with the turn signals on it out of that site, I would like to know what the other colour wires are for.
Also, what does the flasher unit look like? Is it the black square piece in my photo above (immediately to the right of the yellow circle)? Is it also shared by the hazard lights?
And are there any thoughts on why that metal box in there is heating up, even overheating judging by the melted plastic around a lead to it?

I can now find no power
And all the while this socket is floating loose with nothing plugged into it:

Of course, it could be for something unnecessary (power windows or similar, but I'd like to know, it's just hanging down to the right side of the steering column.
And, like I say, I find no power to the switch at all now. Any help with those wire colours would be a great advantage to me.

We've now established that the canister was faulty, but changing that hasn't effected a repair.
So it's back to the wires:
![](https://i.postimg.cc/jd9cSkKW/0908-04-wiringribbons.jpg)
This is the 'ribbon' of wires going to the turn signal switch. black with red (horn), green, beige (or cream), pink, red with white, blue with pink, brown with red and finally white.
Yesterday we had power in the white, that;'s gone now. Today we have very weak (according to my test light) power in the red and white.
I'm thinking of cutting into the red and white and putting some direct power to it to see if that functions things. But which wires are the ones to the turn signals on each side?
