Navigation System Install - Pioneer AVIC-D2
As of this point, a lot has happened. Looking at the bundle of wires, the new power cord was wired into the factory harness by crimping the yellow wire to the terminal in the dash, which receives constant power; the red wire connected to the terminal controlled by the ignition switch, and the orange/white wire connected to the lighting-switch terminal. The black ground was screwed to the vehicle's body. The pink wire connects to the vehicle's injection computer via the plastic connector from the kit. Its purpose is to direct speed signals to the nav unit so the navi can calculate more accurate location information. The light-green wire was clamped to the power side of the parking brake switch. This allows the head unit to detect whether or not the parking brake is engaged. Once these were done, the head unit showed an error message until the head unit's sensor initialization was complete. The violet and white wire was clamped to the wire that undergoes a voltage change when the vehicle is shifted into reverse. This helps the navi to determine if the vehicle is moving forward or backward. All of this plugged into the back of the nav unit. View Related Article
