A little more clarification - 1st Uhaul trailer had a separate ground wire , the one I have hooked up today , does not - SAME result, fast blinking - all lights on both trailers work(ed) - on THIS hookup, I'm noticing a low voltage spike that very faintly lights up the trailer brake lights at 8-10 second intervals - mind you, this is when the X5 is turned off, parked, and locked up! - I never would have noticed it, if I had not been packing at 3am.
They (the dealer) said everything is hooked up correctly, but it sure does not seem that way to me.
