Throttle and brake connectors

[shauny2801]

Hi my throttle wire harness snapped of right before sealed joint so couldn't repair it so im looking for a replacement wire harness which has the 2 red connectors for brakes and one yellow for throttle. The problem i have is the cable from control box for these is a blue 4 pin connector the only ones I have an 8 pin to control box connection so don't know how I can work round this?

try Ali express or one of the Chinese sites,chances are you can find a similar cable( this must be a Julet connector?)

As mentioned above, you might be able to find a replacement online, but your best bet would be to contact the bike maker.

If you are proficient with fine wire soldering, you could also make up a replacement harness by buying individual pigtail connectors like these:

Determining the correct pinout could be a problem though.

I think the only option is i can get another thumb throttle which has a 4 pin connector and get an extension to controller as im selling the bike anyway I just wanted the throttle working

 

[shauny2801]

The only thing I wont be able to connect is the brake sensors as they were on the original harness

Soldering? you have to have the skill of "Pedaluma" and others to that,last time I tried solder was flying and was almost crying,thank God for solder less connectors.
