2000 Ford F-150 Starter issues

I'm lost. I first began having issues with the truck not starting. I would get one click and nothing. Battery tested and is fine. Alternater and Starter tested fine as well. I cleaned all contacts off the relay switch. Truck started, but starter seemed to stay on--keep cranking even when in gear.

I replaced the relay switch. I connected the wires again and when I connected the negative wire on the battery it began cranking without the key being in the ignition. I figured that I wired incorrectly, so I tried about every scenario for wiring and always the same thing. Without the key in the ignition the starter began to turn over.

Replaced the ignition switch and the relay switch again thinking maybe I got a bad one and the ignition switch only cost $20.

SAME THING! I just touch the negative battery wire to the battery terminal and the starter tries to crank over.

I've about had it and I'm about to throw in the towel. Any help would be greatly appreciated! Am I continuing to wire it incorrectly which is fusing the relay switch?
