I just installed my z120bt. I am attempting the bypass, thought I had it all right, went out driving, video shut down and message came up about parking brake, I will take it apart and make sure I didn't make the hole in the pin to big and try that but is there any other suggestions? I assume its ok to bundle the ground wire from the deck, the ground wire from the ford harness (its a f250 if that matters), the parking brake and the moved mute pin all together or do I have to run a seperate ground for the moved pin and the parking brake by themselves?
Frustrated but want it to work....
