Fabrication error: wrong PAS connector?

[C.B.]

So I’m building a third bike with the same equipment as every other time; namely a ”Shark” frame battery with an integrated controller.
I ordered this from bmsbattery.com, nothing unusual about that.

However.. as far as I can tell, they’ve put the wrong connector for the PAS coming out of the controller.
It should be an orange 3-pin connector, but it’s green with 4 pins.
The included PAS has the standard orange 3-pin alright, which manifestly will not meet with the battery, of course.

I went to check with my other 2 bikes just to make sure, and yeah, coming out of the battery is the orange 3-pin, not a green 4-pin as in this case.
I’ve also googled far and wide for a 4-pin PAS and have come up short. 3 pins appears to be the prevailing standard.

What can I do about this? Is the controller amenable for surgical intervention? Or some sort of adaptor perhaps?
I could possibly open it up and try to solder a different cable to it I suppose but I’d rather not. As it stands, I can’t connect the pedal assist sensor.

And no, BMS Battery have not yet deigned to answer my emails about this.
I am right in thinking they’ve made an error at the factory, yes?

Best,

Looks like a green 5 pin connector to me. What I would do is look at the controller and see how many wires from that connector go to the circuit board. If there are only three, then it's pretty easy to figure out power, ground, and signal pendiing some resolution by BMSbattery.

Yes, it does look like 5 or indeed 6 but when one looks close up it turns out there are only 4 actual pins.
I do wonder how they managed..?
