I installed them with the tails, no flickering while running.

Like I said, they work awesome, besides the startup strobing sequence, but doesn't affect them in normal driving operation. Check the pins on your harness, I'm guessing they switched around taillight wiring over the 7 years of production, thats what happened to me.

Let me know how you do, you just need a really small flat blade screwdriver to release the pins from the harness. Obviously do it on your cars wiring harness, the harness for the LED tails is siliconed to be watertight
