I'm going to check all this stuff over tonight again. Here is a possibility.... There's two wires the connect to the starter. The small wire goes to the main lug on the starter relay and the larger wire goes to the positive post on the battery.... I spliced those both cause they were not long enough. I soldered them and shrink wrapped them. Could this be the issue? It's been in the back of my mind this whole time.

When everything goes South I go back and recheck everything that I had done recently.
Yes, verify that the bulk head connector is coupled together properly, maybe one or more of the male/female joints did not seat properly and got pushed back, look it over closely.
Check that the ignition switch connector did not get dislodged, recheck what was done on the turn signal repair,,
If you do not find the issue, it is time to get a FSM and a multi meter and check the circuits.
If you have not done that before do not be intimidated. Folks here will guide you. A cheap HF multimeter is all you need.
