Yes the truck was running and the purple wire went from the ignition switch through the firewall directly to the starter. Any idea why the negative terminal would spark now?

So the starter wire is hot all the time? I would suspect a faulty ignition switch. Unless its hot after the relay, then I would suspect a sticky relay, they do stick sometimes.
Then of course there is the possibility that no one likes, that it is shorted with another wire making it hot.
You will have a small arc when you connect it usually. The thing is how small is the arc, is an interior light or something on? Maybe an underhood lamp?
No need to re-invent the wheel. But we can make it better
the book I have says the starter wire is hot while cranking but that is not what I am observing. Maybe there is a wire short in the dash. I will have to look. The under hood lamp is powered off a junction block on the passenger side of the engine bay. Thank you for helping, I really appreciate it. I need to do some more investigating.
Yes the starter wire should definitely not be hot all the time, if you find it, I'll bet you also find the source of the arc. Hope it's an easy fix for you.

Quick update: this lead me to the ignition switch. Original to the truck and worked before the swap. I bought a new one and now able to crank engine with the key. Thank you for the help. I don’t think I would have checked the ignition switch.
I am still not getting injector pulse. Been doing research and discovered engine speed (RPM) is not logging in OBDII. I have a lot to check/verify with Crank/CAM position sensors, wiring and grounds. At least I am heading in a direction instead of being stuck. Thanks again.
