I'd like to get my stereo working as soon as possible, an Alpine head unit. Right now it will not turn on, unless I jump the ACC from the wiring harness to the 12v constant... I'm using the Metra harness recommended by best buy and confirmed via phone with Metra... Metra-Radio Wire Harness Adapter for Select Mitsubishi Vehicles-70-7005 I then tried jumping the 12v ACC from the harness to this mystery white wire behind the dash, but this did not resolve the problem. This site following shows the 2009 (not 10) Lancer as having a different color altogether... http://www.modifiedl...lation-diagram/ I also found a yellow wire (per above site) from what i believe to be the 3-wire bluetooth harness that connects to the factory stereo. I tried jumping the Red ACC from the Alpine to that, but also no result. My only thought now is that I may have had to connect the hazard-light assembly to get the white wire to work? But I spent much too much time out there today to go and mess around in the dark again, maybe the next dry day. In the meantime, any suggestions? Or has anyone had similar problems? Thank you.
