Sorry long delay been working i have taken a picture of both of what you have asked. To spare connectors not sure what they are for i assume for installtion of thorttle and lightsD8veh know about these but has taken a sabbatical of late.
We need to see the handle bar display panel and the controller for any spare wire connectors.
If those two options don't bare any fruit then a new controller and LCD would work and give you what you need cost about £70 - £90..
The only spare connetors are the white and black and grey and black which are two prong connetor i can retake all other wires have connections allready.A quick look everything doesn't show very well to much of a birds nest, pics will need to be better with wires & connector more definable.
You need a 3 wire connector for a throttle, so you will need to replace the controller and prob. a new LCD display.
Also what lcd any price qoutes?Thank you wheeliepete any idea as to what type of controller i would need given my model of bike?
