LED turn signal problems

I just replaced all my lights with LED's. I also replaced the turn signal relay with a LED compatible one. The problem I'm having is the turn signal is back feeding through to the tail light of the opposite side. So it's kinda like the hazard lights are on when just the turn signal is on but not as bright. When i re-install the old bulbs, there is no issue. I've read all sorts of threads about the led lights blinking too fast or not all but haven't seen anyone have the issues I'm having. Any information would be greatly appreciated.

Check the plug and the led pins. There are two types of sockets that look the same and take a 3157 bulb. The difference being one has a ground on each side and the other has the gounds on one side. Make sure the led pins are matching the plug. u can bend them around if need be.

Did you get it fixed? Im leaning towards a bad ground, and/or you need a "no load" flasher fuse, (depending on the lights you installed) you can find them on ebay.
