OK for the ISCV, no, I don't have it. Is thatthe reason why the idle is very irregular (short acceleration-cut-short acceleration-cut, etc.) as you can hear on the video? It also explains what this 2 pin connector is supposed to be plugged on. This is much clearer to me now
Damn! Should I get hold of a ISCV? Will the engine never work correctly (idle) without this?

Hummm. I'm quite sure the plug on picture 2 was connected to the fans, as I tagged it this way myself when I removed the loom from the donor. A mistake is still possible, but I'm almost 100% sure it is the right connector. Also, there is no oval 2-pin connector available on my loom except the side repetitors. I checked the electric diagrams on the Sierra Haynes repair manual, and I think there are 2 positive (one for each fan, the original fan assy had 2 fans) and one earth coming on this connector. would this be possible? The only difference with the diagram is that it is supposed to be 1 Bn (earth) and two Bk/R (12v +), but I have 1 Bn (earth), 1 Bk/R (12v + I guess), but 1 Bk/B.

I made other pictures so you can see where it is connected. Well, there is this hose supposed to be connected to "the hard pipe from the fuel tank", the other one is connected to the inlet manifold.
There is no inscription on the box itself, but there is a sensor on the pipe going to the manifold, and this sensor is Ford marked with a number. May be you can find out what parti it is on your "bible"

Anyway, I disconnected both hose and electric connector, and it makes no difference, the engine is working the same. The only thing I can say is that the push-fit fitting it is connected to on the manifold is a vacuum, I put my finger on it to check.
I'd like to remove it completely, but if it is an emission control device, I'm afraid I will have to keep it. So where shall I connect this hose supposed to be connected to the fuel tank? Big mystery. If you have any idea...
Thank you very much.
