Ok here is the story.
I did the bypass, by moving the mute wire to its new position, then connected it with the barking brake line, then used a small wire I found around my garage to ground them to the metal part in the car.
After I did that the D3 did not turn when I start the car. I thought it might have been the fuse in back of the D3…but it wasn’t.
The wiring harness that was used for installing also has a fuse on the harness; I took it out to see if it blowout, but that fuse was fine also; but when I replaced the fuse into the socket after inspecting it the D3 worked! (it appears the problem was fixed by moving and replacing the same fuse in the harness) I drove around the bypass worked like a charm!
PROBLEM: This morning I started my car and the D3 doesn’t turn on. What could the problem be?!?!?!
It’s a 06Chrysler300. I just got the D3 professionally installed about a week ago.
