The IMC Audio GWH406PIO wire harness is a fast and easy replacement from your factory radio to an aftermarket radio. With easy color-matching wires and easy connection to your after-market radio, the IMC Audio GWH406PIO immediately eliminates cutting OE radio plugs. Without the help of IMC Audio GWH406PIO you would have to manually test each wire to connect to your after-market receiver and you would have to cut the OE radio plug as well.
