Can you identify these conectors?

I disconnected the pedelec sensor on my bike to enable use with throttle only (it does add quite a few miles to the battery's range, as the motor does not run when you don't need it to).
However, I would like the option to be able to use the pedelec mode too when wanted, so should like to fit a switch. But I have never seen the connectors in the sensor lead before (pictures below), and I wonder if anyone can identify them? They are about 1cm wide.
Also, the lead has three wires, and I suppose it is unlikely that I will find a suitable triple-pole switch capable of being mounted on the handlebars (or indeed elsewhere)!

Any suggestions gratefully received...

Possibly JST SM. They are fairly common for throttles. There was a thread awhile ago with Aldby working out where to get them. I have a few SM shells and terminals.

I'd imagine that only one of the cores is the signal return to the controler, so you'd probably only need a single pole switch in this line.

Ah, thanks for that tip. But how can I identify which one, or is just a question of trying one at a time?
And what would the other wires do? Is there a standard colour-coding in these kinds of circuits? The wires are blue, red, and black.

I think the one at a time approach is probably the best way, the pedelec sensor on my wisper only has 2 cores, so it's possible that one of yours is redundant. In which case, convention would suggest that the circuit is between the red and blue. If it were me, I'd start by pulling the red one, and seeing what happens - just a guess though.
