Main Radio wiring harness WITH steering wheel control interface built inÂ
This harness connects to your factory wiring and provides the wires needed to install an aftermarket radio. Some of the wires needed to install an aftermarket radio are communicated through CAN bus. The small box is a CAN bus translator. The following wires are transmitted from the car to the radio through computer signals: Swithched12v, Illumination, Reverse, Parking brake and Vehicle Speed Sense. the small box reads two twisted wires CAN+ and CAN- and translates them into analog signals your new radio can read. It also translates the factory steering wheel controls into a signal your new radio can understand.
