Default new battery cables, now no power?

I put new battery cables on the truck (positive and negative, both batteries), I am absolutely sure that I have everything hooked up the way the old cables were, but now I have no power. No lights, no start. Cables are oem, just like the ones I removed.

Is there any breaker that needs to be reset, or anything else that needs to be done when re-connecting the batteries? Both batteries read 12.X volts. And had no electrical issues before, I just replaced the cables because they looked like they were corroded, and I usually replace the cables when I get a new (used) vehicle.
