If using a SWI interface, connect the green wire on the SWI interface to the red wire from the red 20 pin connector. The SWI interface must be programmed for Version #1. Step 1. Pre wire the RAD-18 wire harness to the aftermarket stereo wire harness. If the aftermarket stereo has a mute wire, cut the brown wire as close as possible to pin #16 of the RAD-18 harness and connect this mute output wire to the stereo’s mute wire. The amp remote wire (blue/white) must be connected to the stereo’s remote wire. Step 2. Connect the black 16 pin and the red 20 pin harness to the factory radio harnesses.
