Ride1Up Rev 1 upgrade 99% successful but I'm confused about the speedometer wire.

[heynow1010]

I upgraded my Rev 1 FS from 52v w stock controller to a 60 v w Motoberry controller. Because this bike has a place for two batteries and space for two controllers I have the original 52v controller controlling the display (w lights, turn signals, horn, brights,) and the 60V controller with a keyed thumb throttle and voltage display controlling acceleration. At 4:50 into the video below about this exact upgrade the author says to leave the white wire connected to the 52 volt controller so it will read the speed.

.

Silly me I disconnected the white wire and I don't know where to connect it to the original 52V controller or how. I am using an app on my phone to get speed currently but if there is an easy way to connect the white wire back to the original 52V controller so it will send speed info to the display I will do it. I will also write to "Ebike Adventures" who made that video. Of the many excellent videos this guy has done he has one video about how to wire this overvolt upgrade process and the one above which tests the results but no clear diagram of where to connect the white wire to the original controller. Any help is appreciated. This is my first ebike and first upgrade.

Should be a simple fix. The white wire should connect to the motor connector from the stock controller.

Ok yes makes sense . I have an extra stock controller and I took a picture of the end of the controller wire connector that formerly connected to the main motor wire. It appears to be totally female comprised of three thick pin holes for the phase wires and eight tiny pin holes for hall wires? Obviously you are suggesting the speed wire is likely one of the tiny pin holes . What’s the next step here please? I was hoping to avoid slashing into that thick controller motor wire. Is there any alternative way to get the speed signal to the speedo display? I can’t imagine trying to stick the tiny strands of the white wire into those tiny holes. Thank you again for all your help E-HP. You’ve been a major factor helping me realize this build.

Didn’t you cut off the male connector from the motor side? Use your meter to identify the pin for the white wire. Then you can line up which female hole to use.
Or plug the old connector in, and connect white to white.
