Hello,
I posted here before on advice about my dual ebike kits. They just arrived but I want the Bafang twist throttle to control both motors. From EbikeSchools.com’s video he demonstrated a wiring diagram which shows different wires compared to my throttle. (Below I have attached the diagram)
Here is ebikeschools.com’s video: https://youtu.be/SHXQr2MPJS8
Here is a video a made https://youtu.be/KghdbxznKTM

*Just a update* I have opened up the controller and following the wiring from throttle, the contacts are labeled black=G1,blue & green are connected to a different wire, yellow=DM, red=TH, white=TS. Here is a recording below to help better illustrate my problem.

Cheers :D
 
What is the model of Bafang throttle? Just key switch and throttle? And what is the make and model of your controllers?
I don't see an attached diagram... is this the one to which you refer?

Hello, the diagram I was talking about was in EbikeSchools video so didn’t want to be repetitive in my post. The model I believe is a wuxing 81x.
For the controllers i’m Just using the ones that came in here https://s.click.aliexpress.com/e/bJjm46Ys and here

Here is the diagram i’m following in regards to 2wd motors

I can't locate any wiring diagrams for the Wuxing 81X. With those components I would expect 5 wire hook-up. As you may have seen by now the manufactures have a sense of humor about the wiring colors they use. As there doesn't seem to be any true set in stone rules. The safest and most accurate check of the throttle wiring would be to open it up and see which wires go where...

The hall sensor wiring connections are as follows...

And then you can see which wires go to the keyed switch. ( caution, do not accidently mix the hall sensor low voltage wires with possible high battery power voltage!)

Then to determine where to connect to the controller(s), from your links the make and models cannot be read. Perhaps there is a wiring diagram for them... and verify which one your using for throttle power and ground.
