    Tach wire off coil?

    I need to wire in my window switch for the new nitrous kit, On the ls1 cars, the tach signal is a light green wire on the passenger side, does anyone know if it is the same on our trucks?


    It's a 01 5.3 Silverado.

    I'm assuming it's the green one on this plug...


    I'd rather not tap off anywhere NEAR the PCM lol

    Doesn't really matter if it's near the pcm or not, it all leads back there...
