Is there a white wire from the module to the coil? It should go to the 12V side.
Wiring help, rewired evo no spark?!
I know this an evo, and worse a softail. But I also know you fuckers have some serious knowledge, so I'm hoping that the mods will let it pass. So I gutted the wiring harness on this 99 softail I picked up, and tried to re-wire using a simple diagram I got from Rudehog on here. He was actually tons oh help, trying to somewhat style the bike after his old one, only cuz it's probably the most tastefully done softail I've seen (outside of Danny F.) but I digress...
Here is the diagram I used:

I added some shitty drawing using paint on my computer trying to show where mine is different. I'm trying to use the stock ignition module, and my coil only has two pegs (dual fire?) not three.
And here are some more pics just for reference.

So the lights work, the starter cranks, but I got no spark. I got fuel. I soldered and shrink wrapped the connections form the cam sensor to the stock ignition module, and used my manual to get it right from my ignition to coil. I have a wire running from the ignition swith to coil. My multimeter shows power to the coil, but I got nothing.
I'm about ready to scrap it all and start over with new components, ignition coil whatever. Everything worked fine before I took it apart, and I'm inclined to think it's my wiring...but this is frustrating.
Am I missing something with the lack of kill switch/additional ground from coil or something? If the module is fried, will it not spark at all? I'd appreciate any help, even if it comes with "your an idiot" attached.

If you followed the diagram posted it appears fine to me. The 7 pin Screamin' Eagle is Harleys high performance line module. 7 pin refers to the number of wires on the plug-in connector.The coil is polarity neutral so it should be fine.
Here's a check for ya.
First of all be sure all grounds are clean and tight.
Remove the timing cover over the sensor. Turn the engine over manually (get the rear wheel in the air,put it in top gear and use the rear wheel to turn it over if no kicker) and make sure the open area of the cup is NOT in the sensor gap. Before removing the timing plate mark the timing plate with a magic marker so resetting timing is easy. With the test meter set on DC volts probe the module connector to the sensor from the back of the connector at the red and black wires w/ignition and kill switch on. Should read about 5 volts. If not it's toast.
If it passes lemme know and we'll look in a couple other areas. But sounds like it's done.
This is the timing sensor I refer to.
