I wish I read this post before the last one. Yep it's like those old orange, gold, and chrome boxes direct connection used to sell. Da ! Can you tell, I like aftermarket ignitions. I remember a guy had this potentiometer type system built into his gas pedal for the gold box, that would give it more juice as he increase the RPM's. Okay I've ID'd what I need and thanks. And hopefully if I keep the vacuum valve on that hose the interior vent keeps functioning.
