Coil Pack
 

Hey all,

I have a couple of questions regarding the F-150 coil packs. I have an '07, so I'll go with that year, but they're general questions. Is it triggered by a short or an open? What vlotage is the trigger? I would think 5V, with a 12V source, but no one accused me of knowing as much as I think I do. How many wires? I'm no where near my truck right now, and it'll be a while before I get back to it, I'm just wondering... Thanks in advance for any/all help.
