installing a sound system and was wondering if anyone knew which/where the wires are to tap for the 12v trigger wire and where an easy location to tap for the rca converter is. this is a friend of a friends new car so i really dont want to be ripping the dash apart to get to a few wires. If anyone has done a system in the 2012/13 rio please let me know what wires to look for or if someone has a wiring diagram. The headunit is remaining stock so the usual procedure for installing the trigger wire and rca outputs isnt possible. thank you for any help you may be able to provide.
