Yeah, tahts what I’ve had a couple people tell me, but I simply can’t see anything. I’m going to get a test light and see if I’m getting power to those wires at all. If I’m getting power, then I know its a ground, if not, then who knows where the problem is at. --- _[View the full topic](https://forums.speedlife.net/t/downtown-3-30/188916)._
