sciroccotune 0 Posted August 5, 2012 Hi guys, Just need some help with the throttle switch wires on a 1.8 16v, I believe that pin 1 is at the top and it's the black yellow wire but then I'm lost and the plug on my car is not original. It's the connection on th TB. If any one gets the chance to look 100 internets to them Cheers. Quote Share this post Link to post Share on other sites
