I have a 2006 Buick lacrosse. I'm installing a new head unit and am trying to figure out how I would find the car speed signal wire. Any help would be appreciated.
You can cap or tape off that wire. It's not essential to connect it.I have a 2006 Buick lacrosse. I'm installing a new head unit and am trying to figure out how I would find the car speed signal wire. Any help would be appreciated.
