Ignition module 04 mastiff

I just installed the wire plus kit to get rid of the ehc module. Basically for no reason other than I've had to replace the ehc once before. What the real problem was is the ignition module, the little silver box with a knife going into a heart. I think it's a thunderheart or thunder mountain?? Does anyone have a working one or know where to get a new one?? Should I try something different? I would really like to just buy a new one and plug it in instead of buying something different and wiring it into the coil. Any help would be greatly appreciated. Thanks:bang:

If you get a different model you will be able to adjust your timing for a bit more performace.

I know. I just don't want to run 3 more wires through my frame, getting kind of crowded after the wire plus kit. I was just hoping someone new where to get a plug in replacement one. Is that stock one known for having a lot of problems? Or is it just mine. I have replaced the EHC once, 2 starters, I think 2 voltage regulators, and finally just installed the wireplus kit and now the ignition module is on the fritz :( All of this was over a course of about 3 years or so. When the bike runs it runs good. I would be so happy if it would just start every time I pushed the start button. If anyone knows where to get e replacement that would be cool

04 is cam sensor. I think you gotta have an 05 or newer to run the programmable thunderheart but I may be wrong. Think dyna2k or crane... you still have room in the center downtube and backbone to run wire from nosecone to coil.
