Well, the big current carrying wires are easy. The old mobile connector doubled up on those, so should be easy to figure out which one goes to where. For 240V, it doesn’t even matter if you get them backwards, but for 120V, it would matter.
But the new cable with the two extra wires is interesting. I suspect the extra ones are for a wand heat sensor that the old mobile connector did not have. Since your old mobile connector doesn’t have that functionality, you’d be able to ignore those extra wires.
So, yes, I think this is all possible, but no I don’t have a wiring diagram. But the owner of this company does since this is the kind of thing they do:
QC Charge - Home
In fact if you sent them the parts, they’d probably splice them together for you.
Personally, I’d just buy a new Mobile Connector and call it a day, but looks like you have the extra wand somehow…
ps. The white and orange wires are the heat sensor one probably and those are the ones you could ignore.
