Wiring diagram?
Wiring up a new electric bike not sure about wires, need to know which wires connect to battery and wheel motor.
Also, what's the difference between speed throttle and accelerator.
The wheel motor is from a different source.
What are the multi plugs for on the wheel motor wire.
Many thanks in advance.

Man, they cannot even spell Brainpower anymore, Wonder if that is a real unit or a copy. Not that "Brainpower" was any good. I had two. They weren't too good. Too weak. What kind of motor do you have.
Throttle is throttle. The other one is pedal assist sensor,
Take your voltmeter and verify that the + and - signs molded into the plug are not lying, Then the red and black leads from the controller go to + and - respectively. I assume those pictures of the controller are the sellers pictures. Does your controller look the same?
Is this what they sent for a motor cable? Does your motor have the round 9 pin plug that fits the round connector in the picture? Your wiring will depend on these answers.

The cable came with motor and has the round plug do those 3 big wires go to the 3 phase line, colors match.
The red and black wires on controller do they go to battery one says negative electrode (black) other says Hal sensor.(red)
diagram came with actual controller.
48 V 350 W motor It's a very nice looking wheel so far, I will know better when its all working.
I go a deal on the battery so it's a cheap conversion on a Marin Aluminum bike, always wanted to build an electric bike.
Thanks
hope its OK to post ALi links

Yes, the heavy ellow, green, and blue wires from the controller go to the same color wires on the motor cable. However, you habe the w rong connector for the six thinner wires on the motor cable.
It would be nice if they used the typical 6 pin Molex plug to match the one on the controller like in the picture below. . Since they did not, one approach is to cut off the two connectors onyour cable, cut the rectangular molex plug off the controller, and wire them color by color together. That's probably better than buying that connetcor, along wth six pins, and rewring the motor leads
to match by color.
Yes, you understood the battery right.
If you had bought the brake levers, throttle, and pedal sensor form the sma eseller as the controller, the connectors might macth. You will have the same issue there if they don't match.
The controller is self learning, so it should not really care about matching up the motor wires. How it works is you connect the learning wores together. Power up. The wheel will turn brief and the controller had figured out the wire pattern. Then you disconnect the learning connectors and it's ready to use.

Got it all figured out?
I usually start with the basics. Wire the battery (positive & negative) and the throttle, and it should work. I've had problems with the throttle wires not matching, in which case the throttle doesn't do anything. Most of the rest of the stuff is optional (although some controllers require the hall wires/others not).
Just don't disconnect that "master switch" or nothing will happen, lol. I like to put a toggle switch in there so I can turn the bike off - so that there is no battery drain when the bike is parked.
