The new controller arrived and turned out to be 9 pins for the IT4 cable also, however it works correctly so the first controller I bought was faulty. Everything worked except the pedal assist and after a lot of head scatching and downloading the KT LCD5 manual as the manual that comes with it is basic and does not include the advanced settings, I changed the C1 parameter to 07 and that fixed the PAS. If you upgrade a Pure Free City ebike and keep the existing PAS that setting needs to be changed for PAS to work. Advantages of the upgrade are a thumb throttle for easy starts, speed control or simulated torque control, 5 power settings instead of 3, top speed up to 20mph. The new controller, throttle, display meter, IT4 julet cable and a 9 pin motor extension cable came to £97.95.

I bought the components seperately but the julet cable and controller have all the correct pins and colour codes, it is 9 pins controller to IT4 cable. I have now ordered an 8pin controller and 8 pin IT4 cable. I will post again when I have tried them.

Update - I have reconnected the original Controller but plugged in the new KT LCD5 display and it switches on, it wont function but it is looking like I have a faulty new controller?

Thanks but there is no battery in the KT LCD5 display

I have a pure free city ebike and I am trying to upgrade the controller, display and add a throttle on the lines that I have read here regarding the Pendalton Somerby upgrade. I have bought a KT36/48ZWSR 15a controller, a KTLCD5 display and a 1to4 cable to match. Everything plugs in and I have checked that there is power to the controller but the display does not switch on. I have unplugged everything except the controller and display and still the display wont switch on. Any help will be appreciated.

Thanks for the promt reply.

Great post. What length 1-4 Cable 1400, 725 or 295?
