I seen a thread on getting a wire into the cab threw the firewall and the fellow took the car into a audio install shop to get a wire from front trunk into the car
My Question is has anyone run wires from the front trunk space and threw the firewall I am installing a escort 360 Mac ci and I need to get three phone line cables from the front and into car there does not seem to be any grommets and I took it to Acura for a service and asked if they would drill a hole threw the fire wall and they won't because of liability issues
any ideas other than a audio shop? thank you
