I have got a 1000w 48v motor kit and it has a standard twist throttle at the moment with red, orange and green LEDS as battery indicators I’m wondering if I could install One of those throttles with volt meter and key ignition if I can how would I do so as I’m new to this? Also it’s a cheepish kit from eBay and there’s nothing on the controller saying lock or anything to do with ignition? Thanks for reply’s

You can, but you'd need to do your own wiring. I can't advise you how to do that without knowing exactly what you have and which exact throttle you want to add.

You'd need a two wire output on the controller for "Electronic Lock". That's what mine has and it links perfectly to my throttle with digital display and key lock

I have a connector on my comtroller with a red and black connector wire will this be for the lock?

Your present throttle must have 4 wires: 5v, ground, throttle signal, all for the throttle operation; and 48v for the LED panel, which will take a spur of the throttle ground.

A throttle with voltage display and a switch will have an extra two wires for the switch. There are three ways to use it to disable the bike.

1. If you have no PAS, you cut the red wire to the throttle and join the two ends to the switch wire. That's the easiest, but won't work if you have a pedal sensor. If you have a PAS, you'd have to cut the 5v wires to both the PAS and the throttle, join one controller side end to a switch wire and the other switch wire to both the PAS and throttle 5v supply wires. This will leave the controller still switched on draining your battery at a very low rate - maybe 4W.
2. Find the ignition wire to the controller if you have one, cut it and join the switch wires to the ends. That switches off the controller completely.
3. If you have a battery switch, open the battery case, unsolder the wires and join them to the switch. That only works if it's a battery switch that stays in possition. Some of the press-button types are momentaru switches and only provide a signal to the electronics to change mode from off to on and vice versa. In that case, you'd have to switch your key switch on and off each time to mchange mode.

Thanks for your help I sorted it now. All i done is cut the red wire from display(sw900) Next to the connector and the red wire coming from controller that was connected to display I plugged the yellow cable from throttle into it and the other half of the red cable that I cut I plugged the blue cable in. And the other 3 wires connected to controller everything works perfectly when the key isn't turned on there's no power to the lcd but powers up when key is turned. Eventhough it works fine would this method be OK for long term or would it burn or fry something? Lol

It'll be fine. The red wire to the display is the ignition wire. The display has a latching switch that connects it to a wire (normally blue) that goes pack to the controller to power it. All you've done is added an extra key switch to the same wire.
