@tonictinsk apparently there are a few version of the cable out there.

It is possible that the first cable would work if you trim it, but I'd be careful with that since you do not know if any wires are crossing etc You will need to know the spacing between the wires to fit your connector. You can of course always try it out and let us know if it worked. You'd only be out a few £
