2007 Honda Civic Si - ECU Pinout/Speed Reference Signal I am installing a new headunit in my 2007 Honda Civic Si. The headunit utilizes several car signals for operation. One signal is difficult to find.
Since the headunit performs navigation, it needs a car speed reference signal. Does anyone have an ECU pinout or know where I can tap into the car's speed reference signal?

Although a non-common wire @ an injector will give you a great engine speed signal, it's not quite the same as vehicle speed. 
I realize this post is very old so you probably won't get this, but. Since you have an Si you're lucky. You can find it as the blue wire next to the purple accessory wire at the radio harness.
