Here is some info.

 

my plugs look the same, thats the only other thing i was wondering about, cause i still dont know where that wire could go, except for maybe there haha. But I did figure it out, its the resistor. its like a 20$ fix, thanks so much guys.

 

I caught the thread too late, but I was going to say to check the resistor because mine is doing the same thing. Sometimes it works sometimes it doesn't and I have to wiggle the resistor wire harness for it to come on. I am just too cheap to go buy a new one as long as it will come on and work for me.
