What is this for?

[Andy1865]

Hi all, i wonder if someone could shed some light on what this yellow connector is for, sorry about the bit of a blurry pic?. Have also enclosed a pic of the controller.
Thanks all.

Pas, ext speed sensor or throttle all use a 3 pin set up in the same sequence order with julet.

I have a red plug for a light I can't remember if its 2 pin or 3. But according the Chinese dude that sold it on aliex it requires a 48v bulb whether that's right or not I'll never know.

The julets are coded for pin out, Red/2 , Yellow 3, Blue /4 etc,etc.
