As already stated, both your statements are correct. Two additional comments. First, there's nothing magic about using #4 for the tach. You can use the trigger wire from any cylinder. Doesn't matter. Use the one that routes the wires the way you want them. Second, don't forget to program your tach per the Speedhut instructions. For this setup you'll use the 1/2 Pulses / rev. setting. Which is not the factory default. I've seen many (maybe not you 
) forget this step and their tach doesn't read correctly.
