Hello.

I hope I'm posting in the right section

Would someone be able to help me checking the correct connections with a Fiido controller?

The controller model is WK3615YS, a 36V 250W model.

I bought it online as a replacement kit (display/power switch, headlight/horn, throttle) to install in my bike (which had a damaged controller and lacked a throttle) not knowing it belonged to a Fiido e-bike (long story)...

It is supposedly from a Fiido D2S, but some connections were damaged and the kit was incomplete (no switch for light and horn).

Right now I have correctly connected:
- two 2 wire plugs for the brakes (yellow/black);
- 3 wire plug for throttle (black/red/green);
- 3 wire plug for PAS sensor (black/red/green);
- Controller plug (4 or 5 wire), G20 model.

I have another 3 wire plug (red/black/yellow) that matches the colours in the headlight plug, and when connected to one another the lamp turns on as soon as I power up the bike (I guess they're supposed to be connected??)

Then the real question:
There is an extra 2 wire plug (orange/black), and two more wires with no plug (also orange and black). Any thoughts on what are these supposed to be?

Thanks in advance!IMG_20201208_230522.jpgIMG_20201111_152406.jpg

I got the instructions from Fiido technical support. It's already on another topic:
