where can i find a compact 500W controller ?

There's no reason not to try it. Other than you might be out ten bucks if it doesn't work.

yes i am usually willing to try if it won't strain the bank. The Y has been ordered along with a HIGO pigtail and I found a JST SM pack of connectors with pigtails for cheap on amazon since i don't have/want a crimping tool.

two more questions ( group of ) ... one old... one new.

- any idea why there are 2 ebrake connectors at my controller ? isn't that redundant ? i assume front OR rear brake activation should tell the controller to stop the motor. why would one then need two independent circuits ?

- does polarity matter in these eBrake circuits ? I assume it sends 5 volts out and pulling the brake lever closes the circuit. It's just a two pin cable so i would think it wouldn't matter how leads are connected.

SOLVED : so all my parts came in, were correct and the wiring up was relatively simple. Never got an answer as to if polarity is important in the ebrake circuit. some research on this forum did declare if you wire up wrong, motor will only work when brake IS applied.... that, of course, is no bueno. I just went with the trial and error method. Either polarity does NOT matter or i got lucky on my first test. I had already soldered leads together before i thought about testing, but once in a while I get lucky. I tested bike on a stand and with ebrake circuit plugged in motor was dead at brake application just like it should, but as soon as i unplugged it, motor would try to do its thing even with brake clamped hard. So bike is much safer now. So stupid for me to ride around without that safety feature for a year....

In all parts costs about 22 bucks and an hour or two to install. The price i could have paid for not having it could have been astronomical.

Thanks to everyone for the help and advice !
