Yes sir, I think that helps! Thanks!

After seeing yours, I realized that since I don't have a tach or vacuum gauge at either end, chances are that the bulb hole behind each of those areas are probably the two that shouldn't have bulbs in them (besides the two indicators at the bottom for 'over speed' and 'whatever-the-other-one-is').
