Moved your thread Joel and you will get more responses over here in Cherokee Chat. Introductions are just for a welcome from other members.
Some more help will be better given if you explain the problem and tell which signal wire you are refering to.

That's the way the aftermarket ones are wired. Never actually looked into the factory ones. I suppose they are the same. It is a direct relationship to how frequently the coil fires. Thus the negative side of the coil gets that number correct or the engine won't fire.
