2012 Coupe Speed Sense Wire
 

Alright I am in the middle of my audio install here and I have a question. Where the heck is the speed sense wire for the '12 Coupe Manual? Using this link it says pin 18 is the speed sense wire. Well my pin 18 is missing... Only one that doesn't have a match in that wiring schematic.

Any one else know where to tap into this wire? This is really annoying me and need some help!

Thanks guys!

You really don't need that input. Just tape it off and tuck it away.
