I tried installing this kit today and ran the power ground and ignition into the fuse box. I can not get it to work. I tied into the power side of the fuses. When I hit the "M" button it does not function (light up). I also am not sure which wires to route for the speaker purple and gray or orange and blue. I have the kit from becker and it comes with the RCA jack. I tried using it but its not functioning, mute does not engage. I am not sure if the module is broken or I don't have power (although I check power and get 22 V)?? Any ideas/ advice?
