It's definitely 'coil in cap'. I'm kind of confused by the 'one wire' that I keep hearing about. Does that mean that it only needs one wire hooked up, although there are other wires, or is there a model that actually only has one wire? Where would I look for a part number on it? That engine bay is so big that I have to get in with the engine to get to the distributor, and I'd like to spend as little time in there as possible right now.
