This is where we are. Your throttle has four wires from the controller compartment:
Yellow - battery voltage for LEDs
Red - 5v for throttle
Blue - ground for throttle, joined to black for LEDs
Green - throttle signal
The red, green and blue run to a 6-way connector that's shared by other wires that can't be traced in the photos.
You cannot buy or replace the throttle with the correct connector because the connector is shared. You need to remove the pins from the connector, then you could get a throttle with the right pins to push in. You remove the pins by depressing the little barb with a tiny screwdriver or a darning needle or something like that
I can provide you with a throttle with the correct three pins for £8 including postage. If you show a picture of what's on the yellow wire I can match that too.

Hello again my friend,, I thought for one minute I had been too much..
I have still got the throttle from my sons friend who is selling his bike. As I mentioned before we connected it colour for colour to my wires where I had cut the broken throttle off but nothing happened when I switched the battery on. The battery level lights all lit up but no lights on the throttle.
Since then I contacted you again and you posted the wiring advise above,, Today I have just tried his throttle again and connected
red to red.
blue to black.
green to white,
yellow to green,,,, again nothing,,, the only wires I have not used is yellow and brown which are on his throttle,,,, so I am stuck....I am itching to have the new throttle from you that you kindly offered but am a bit concerned it might be something else that the throttle affected when it disintegrated.
We know for a fact that the throttle that we have borrowed was working normally.

The yellow and brown on the new throttle are for the switch. They don't do anything, so leave them disconnected for now.
You connected correctly in the description above. Now you need a voltmeter to determine what's wrong. Check between the black and the yellow/green. It should be battery voltage. With the three throttle wires connected, check between red and blue/black. Should be 5v. Check between blue/black and green/white. It shpuld change between 1v and 3v as you oerate the throttle.

Thank you for your reply,, now I am going to look a complete idiot. I have a meter which I have had for years but have no idea how to use it other than checking fuses.. I have added a picture of it in the hope that you can tell me what to set it to....thanks again

Two clicks from the off position where it says V with a straight line over the top. If it hasn't been used for a long time, it's battery might be flat, which will cause it to misread. If you can, check something that you know the voltage of first, like your car battery, which should be about 13v.
black/yellow/green nothing
blue /black - green/white 1v-3v when throttle opened gose to 5v
red/blue nothing.

The first result indicates that either the yellow isn't connected at the controller end or it's broken somewhere.
I don't understand result 2. Is going between 1v and 3v by itself.
Result 3 doesn't add up with result 2. Can you check again.

The reason the readings didn't make sence was because when I opened up the controller compartment and eased all of the connections and wires out the main plug feeding the throttle had come adrift due to the retaining missing and I hadn't noticed. I have reconnected it and the throttle is now lit up and working,,,BRILLIANT I AM SO HAPPY THANK YOU SO MUCH.
The spare yellow wire that you told me to see where it went seems to be going to a connector to the red wire from the battery. Now that the borrowed throttle is working would the seperate light switch cable to the yellow and and browns so that the built in switch on the throttle will work.
I am just trying to understand what I can and can't do. When I decide which type of throttle to have I will be raedy for a quick install..
I cant explain enough how much my bike means to me neither can I express enough word how grateful I am to you personally.
If you lived nearer to me I would love to take you for a pint...
sorry my typing is getting worse,,, what I meant was could I connect the red and black cable feeding the seperate switch, to the yellow and brown cable so that I could then use the switch on the throttle.

You can use the switch for anything you want. The brown and yellow are just one wire separated by the switch, so you can use it to make or break any connection. If you want it for a 36v light, like the Banggood one, you run the negative from the battery directly to the light, then connect the positive to either the brown or yellow wire, and the other one to the light's positive.
You could use it for the throttle as well if you want. Cut the red throttle wire and connect one end to the brown and the other end to the yellow.

Just a tad confused,, I understand that the yellow and brown can be used to interupt/switch anything,,, what I wanted to try was to disconnect the red/black wire from my seperate switch and connect them to the yellow and brown on the throttle...If I can does it matter what goes where, yellow to red or black

Without knowing how your existing switch is wired, it's difficult to say. What do you need a throttle switch for, anyway?
