摘要

OK, let's just put it out there. Aftermarket installation technicians have it harder than residential technicians when it comes to wiring. Why? Because the vehicles have become so much more challenging to work on. If we look at the dashboard, the simple dash cavity has become an aftermarket "perfect-fit" nightmare. We used to get excited if the dash cavity would be a double-DIN so we could add a double-DIN head unit, or perhaps a head unit and an EQ. Now we get excited if we are lucky enough to get a standard double-DIN head unit. The audio control buttons have become spread around the center console like contraband items around the Bieber household! On the residential side, there is still sheetrock, Romex, and a large electrical panel in the basement. And switches are typically located about three-and-a-half feet from the floor. Now, it can be argued that the high-tech home of the future is becoming more complex by having low-voltage control over high-voltage circuitry—in other words, giving your iPhone the ability to dim the lights and lower the blinds. In the car, we used to use relays to accomplish these tasks (or more like honk the horn and flash the parking lights in an alarm install), but now, because of databus networks, we need specialty interfaces to communicate with the vehicle. In the home, that isn't necessary yet.
