RB won't turn over

[PS13 DRFT]

I just recently got one of the Wiring Specialties wiring harnesses and before that I had not ever started my RB. I connected everything, and when I turn the key the fuel pump primes, but when I turn the key to "start" nothing happens. I hear the relay click, and that's it.

Then I found out the spade connector wasn't giving any signal, so I tried to bypass it and wire power straight to the spade on the starter... while the engine turned over, it would still not start.

Any ideas? I'm stumped at this point.

Probably grounds.
