hi again, this seems to be the closest thing I can find

http://www.ebay.co.uk/itm/24V-250W-Electric-Speed-Controller-Box-Brushed-Motor-E-bike-Scooter-/160835983855?pt=UK_Motorcycle_Parts&hash=item25729259ef

As you mentioned very few seem to use the mini type connector which leads me to think I will have to swap them.
Will I just need to change the connectors on the 3 wire throttle and 2 wire motor? Can I use my old connectors from the old controller (photo above)?

Sorry for all the questions! Thanks again.

The easiest way is to cut the connectors off the old controller leaving about 2" of wire, cut the connectors off the new one, then solder them together with a bit of heat-shrink to insulate them. It's only the throttle and brake ones that you have to change. there's no PAS function on that controller.

Hello, due to Chinese New Year I have only just received my new controller. Just about to take about the snips and get soldering when I noticed something which I am hoping someone on here can help with - the new controller only has a 3 wire and a 2 wire to connect up, the old bike controller has two sets of 3 wire and 2 sets of 2 wires which were all seemingly connected up. I will upload a photo of new versus old....

on the right, the old controller - I banded together the unused leads - then there are the 4 main single leads, BLACK, RED, YELLOW and BLUE,
then 2 pairs, Brown+Blue & Red+Black
then 2 triples, Black+Red+White & Black+Red+Yellow.
My question is which pair do I use and which triple should I use?

The red, green and black are the throttle. You have to connect red to red, black to lack and green to white(?)on your throttle. You should check the black and green pair with a voltmeter when the battery is connected. If they give 5v, then that's the brake connector. You can piggy back you two brake wire pairs, so the two blacks go to the one black and the other two to the green.

You've lost the pedal sensor. Brushed controllers with PAS are hard to find.

You can only get power from the throttle, of course. Your pedal sensor will be redundant.

Sorry new controller on the left, 4 main power cables, RED, Yellow, Black and Red which all match up. One set of 3 wire - which one on the old controller do I match up? RBW or the RBY?
And the two pairs? On the new one I have BlackYellow and BlacklRed on the old one I have BlueBrown and BlackRed? I assume like for like with BlackRed and BlueBrown to match against BlackYellow? Thanks again in advance!

Black and yellow is for the brake switch/es. The two single blacks are probably speed limit.Black and red is most likely 24v. Check it with a meter. They'd normally go to a battery level display panel, but you can leave it disconnected.

Hi D8ve, I have received the new controller! All looks good. Here is a raw image from their site - just need confirmation on the connections if possible.
There are the usual 4 RED, BLACK, YELLOW, BLUE individual core which I can match up easily, I am struggling to figure out of the 4 mini 3 wire connections; which ones are Throttle and PAS? YellowBlackRed, YellowBlackRed, GreenRedBlack, BrownBlueBlack??

YellowBlackRed, YellowBlackRed = two brakes cut out
GreenRedBlack = Throttle or PAS
BrownBlueBlack = Throttle or PAS

I think. you can test it out just to plug your throttle. It wont kill it.

on the PAS though there are only 2 wires needed, and the new controller has only the 3 wire option - should this be a concern when re-wiring the wires to connectors?
