Dude Most strange outcome. The LED strips work fine (turn chasing from the middle, running, brake, and reverse) with the ignition off, but as soon as I turn the ignition on I lose the brake and turn signal on both sides. I checked with my meter and I am getting the same voltage at the lights regardless of whether it is running or not. All I can think of is there is some noise the engine is introducing that is tripping up the circuit in the LEDs that detects the flash for turn signal vs brake. I am going to have to scope the output and see whats going on, but we are supposed to leave for a trip Tuesday so it is going to have to wait. Its a shame, they look really nice when they are working.Forum moderators are not GD employees--we are volunteers and owners presumably just like yourself.

I suspect your meter is "lying" to you. When testing the negative lead on your meter is attached to a good ground thus the meter "sees" 12V.
What I think is going on is with the ignition on the wiring is not "seeing" the truck's negative (in the 7-pin plug). A quick check could be done by stringing a negative wire from the LEDs to the negative connection coming from the Bargman plug. (I forget if you have a MICTUNING box setup.)
Could be wrong...but easy thing to check.
