What is an "SML" wire on a PAS + LCD kit?

Post by ebike11 » May 19 2018 7:19am

Hi guys
I disassembled my PAS unit on my bike since it stopped working. I was checking it out and noticed it has 4 wires. Black - red + and orange signal.
But there is a purple wire labeled SML. Would anyone know where I should attach it to? I looked in my parts box and i have a couple wire PAS kits but they are all cheap 3 wire kits. These 4 wires are coming from the LCD panel down through the tubing to the non functioning PAS unit. Id like to try and replace the damaged unit with my 3 wire one but not sure if thats possible.
Thanks!
