Hi all, Im new so be gentle with me!

ELECTRIC E-SCOOTER THROTTLE TWIST CONTROL RAZOR | eBay
But I cant work out how to wire it up. :-? can anyone help please?
Thanks in advance

Yes, It would be possible to get your machine working with that throttle, but you might be alarmed at the way it ran. As soon as you switch on, the motor will run at maximum speed with the throttle closed. Open the throttle and the motor will slow, and stop when the throttle is fully open.
Early Powabyke throttles worked the opposite way to others, and for that reason you should purchase the correct 5 wire throttle from Powabyke on the link below. The throttle you need is half way down the page.

Edit:
I've just had another look at this. If your machine is pre 2008, it may not be the correct one.
Have a read of Frank Curran's posting below. He posted a link to another throttle for pre 2008 machines.
If in doubt, contact Frank on the E-mail address also shown on his posting.
