So I got a aftermarket ebay taillight. I must say this wiring is a pita. So the ebay one has a total of 5 wires 2 yellows (turn signals) and red, green and black. So far I have the turn signals left and right working perfectly fine. But the white LED's for the license is not lighting up unless I hit the brake and the brake lights aren't coming on if I hit the brake obv. Something is mixed up. I'm just not exactly sure what it is. Can someone give me a tad insight to this please. I can get some pics if needed.

 

Update, just got the license plate led's to come on when the bike is on. Just need to get the brake lights to come on now.

 

Which one is ground? green or black? and did you just swap the red until you found out which wire was the running light?

 

yes black is ground and I just tapped the red wire around till I got power.... Maybe is possible I have the brake light on and the running light isn't hooked up correctly.
