Just wondering if anyone knows of an on-line engine wiring diagram for a 90 Alpha 1 5.0.

No such thing as a 5.0MPFI Alph I in 1990, so a wiring diagram of what you now have is impossible.
What are you trying to figure out?

There were a few wires in the harness that were not connected to anything. I wanted to see what those were for, maybe some optional equipment I don't have? And my temp gage is not working anymore, I want to make sure I have it connected to the right wire before I start ohming it out.

Even though I put the fuel injection on, the only wires I spliced into were the coil wires, tach wire, and I used the 12 volt and ground wires to the choke to power the ECM.

Here is a wiring diagram from a typical Merc V8 with TBolt 4 ignition.
