This should be easy as pie but for some reason I can't it to work. The right side flashes until you turn the signal on. Then it goes blank. The left side does nothing. I have wired and rewired and can't get it to work. I was also installing a trick flash relay to ensure the LED protons worked with the factory rear lights and to give it some excitement. I have taken that off and installed the original and still same thing. Help please.
