...I gotta get a new camera. Great shot of the horse and surroundings, and still good colors up close. What camera do you use awptickles?
Well, since the edit, it's obvious to me what it's purpose is. Most older cruise control systems work with vaccume. That's just where honda chose to locate that port on that particular manifold. Though if your wrong about it being part of the cruise control system, it would appear to be a head breather to me too. What's that for, a D?
I wish OP would come back and clarify as to what in the heck he's talking about.
And congrats OP, you probably wouldn't have gotten nearly as many replies if you wern't so cloudy. heh.
