I am in Virginia..Was out of Philly but home is in VA now.
What is the issue with the parking brake? Lets explore this parking brake connection issue some, just incase I am missing something here.
The only thing wrong with the unit is the LCD screen is to dark to see. The touch screen functions work just fine, I just need to shine a light on the screen to see where/what to press.
If the parking brake lead is not connected wouldn't I just get a message on the screen saying there is a safety issue or ??
How could I test a unit???
