Re-assembling my bike with the new motor, I noticed that the roll over sensor had two wires pulled out. The middle yellow one is still in, the one on the top marked "up" is pulled out and the bottom one is. I have a light blue wire and a darker one. I'm trying to figure out which wire goes in the top hole and which in the bottom. Can someone take a look and check for me please? It's right behind the battery. Thank you so much!
