Question about accelerator connection with a single 4-speed shift button, intelligent motor controller connection, identify the cables for what they are

I have a smart motor controller model QG7235-18g-002, as far as it is a 72V MISHOZUKI CONTROLLER
as far as the characteristics are
Input: 110V ~ 50/60Hz
Output: 84 VDC
Voltage: 72V
Power: 100W
Angle:120

But until now I don't have a connection manual for which cable is used for what purpose.
The ones I have identified are the 3 motor phase cables, the 5 Hall sensor cables, the two battery cables, the box on and off cable, and the 3 accelerator cables.
with those cables connected it works
but I still have cables to recognize and I would like you to help me identify them, if that box has to put reverse, if it has to change gears, etc.

Apart from that, the other issue is that I have an accelerator with a single pulsatile button that can be used to change 4 speeds, it comes with 3 cables together that I know are for the accelerator and I connect them and it works well, and it comes with another 5 cables that I imagine It is for the connection of the speed change, that is my doubt and I don't know how to connect that.
If you could help me please, thanks in advance

I will attach some photos so that it is better understandable.

Except for the 120 degrees, those are specs for your battery charger, not a controller.
Do you have a link to where you bought it? Was the controller and throttle sold as a pair/set? If they were a set, I'm surprised that they connectors didn't match up. The pictures don't provide the necessary detail to assist, Seeing each connector and conductors going into each would be good. Between a good description of the controller and the functions it supports along with good pictures would help to make some guesses, but to be safe you'll need a multimeter to check things before making the connections.

Firstly thanks for responding
I will answer you part by part
The specifications that I gave you are the specifications that the page provides me
And they are the specifications of a controller, not a battery charger.
I will attach a link so you can see it.
However, one of the photos I attached of the controller shows you one with a label with the model and the very brief specifications.
These controllers are used a lot in Cuba
They are from Mishozuki electric motorcycles

Continuing to answer your questions...

Throttle and controller were not sold as a pair/set

And I ask you a question about that question that has me crazy.
I have seen many videos and forums where there are 3 speed change cables, usually 1 black color and two colors, but as I said before I have the controller and the motor functional because I have identified so far the 3 phase cables of the engine, the two battery cables, the 5 Hall sensor cables, the two elock cables, the 3 accelerator cables, the two reverse cables, so far it works perfectly for me but I still have cables that I still can't identify, and I have no cables left that come in groups of 3, so I don't know if this controller has a speed change, could there be a controller with a speed change with a single cable or with two?

As for the images I uploaded, I thought that would be enough, however later I will upload more photos with all the controller cables, those that I have identified and those that I have not.

As for the good description of the controller, I cannot provide that because as you will see on the page that I sent you the link they only give those specifications.

Regarding using the multimeter to verify connections, how could I use the multimeter to identify the wires?

Now regarding the accelerator that I showed independent of the controller, could you tell me how the accelerator that does not have a 3-step button works? This only has a push button that I imagine will be used to change each speed?

Thanks again for answering me

If you purchased the throttle and controller separately, then you may be able to use the throttle, but the buttons and power levels won't work, since they weren't designed to work as a set. I would trust a company that sells with those specs. It implies that you need to plug the controller into your house AC wall outlet as the input power, so you'd need a really long extension cord to go riding. Those are specs for a battery charger, so the seller doesn't appear to know what they are selling.
Pictures of each connector and wires going to the connector would be helpful, since there's no other information.

Regardless of having purchased the controller and the accelerator separately, at least in my inexperienced opinion and perhaps it is wrong, but I think that even so, the controller, in addition to some cables for the accelerator, must come with 1, 2, 3, 4 or some cables for speed change, although the accelerator is not compatible with the controller, I would like to know in this controller that I have what the cables are for the speed change

When you refer to power levels, what do you mean?

Here I attach the photo with the controller and the cables it has

When you refer to power levels, what do you mean?

The 4 speeds that you think you have. I would contact the seller and ask them what functions the controller supports.

I tried to contact the seller, they have several contact numbers but none of them give me an answer, however I hope you have more luck than me to see if you can help me solve these doubts

Now, in your experience have you seen controllers with the speed change with a single cable or with two?

Many controllers have what is referred to as a 3 speed switch. The switch wiring has three conductors. One conductor is ground. The other two are signal wires, that when the controller is on, will have a voltage something just shy of 5V (a pullup resistor puts them in the high/5V state). A 3 position rocker switch is usually used to set the 3 speeds. The first/low position will connect one of the signal wires to ground for low speed. The middle position has no contact, for normal/middle speed. The last position grounds the other signal wire for high speed. High speed usually uses a lot more power for a little more speed, so only used when necessary. If you don't install a switch at all, the default is normal/middle speed.

Controllers that have more than 3 speeds usually will also have a display, to show the assist level. Looking at your controller, I don't think it supports a display, or has wiring for the 4 speeds you think you have.

If it supports a 3 speed switch, you could use a multimeter to determine if any of the 3 conductor terminals match the description above. However, note that connecting any 5V wire from a controller to ground could kill your controller, so even if you find a connector that might be for a 3 speed switch, testing it is not without risk.
