I like the thought of reversing leads, but my splices are in the middle. Controller had a white jacketed cable coming out. Cut that and exposed Red, Black, White. Extend that wire and reattach the 3 pin connector and just splicing back in the Red, Black, White. Incoming power is tapped off a 12V cable running to a factory light. Just red and black. I suppose the factory could have used those colors in reverse but I'm scared to swap them as introducing power to the ground may damage the controller. Plus, I am showing 12V at the end of both my incoming power extension and outbound (out of controller) extension.
Frustrating!
