JUST added cruise control to my 2014 manual. Works great, I did a little research on a KIA web site and got wire schematics for the new harness so I did't switch up the connections. The Audio control has 6 wires( orange ,brown, pink, blue, yellow). Voice+Bluetooth has 4 wires(orange,pink,blue,yellow). Cruise control has 4 wires(orange,grey,red,yellow). and Trip cluster has 4 wires (orange,(black & green), red, .yellow). Also used a spark plug socket 13/16 to remove the wheel. Did not need a wheel puller, just loosened the nut and pulled it off.
Took about 45 minutes from start to finish, looks and works awesome.
