Need help diagnosing mower issue. Lx279 John Deere.

I've got an LX279 John Deere. (Engine KAWASAKI FD501V)
That won't start. The (gear) in my New Starter Motor won't connect to my flywheel gear ~ to turn my mower over.
Things to note: I have to wedge needle nose plyers against my Ground terminal and Positive Terminal on my starter soulinoid, to make the gear in my starter motor spin.
My ECU does not light up unless I do this ;along with my other
Idiot lights. ( Don't know what that's about)
My ignition Boxes both have two exposed wires
( See picture below.)

Really I don't know or understand what's up with my mower.
I'll submit pictures that way, my problem is more clear.
