Ignition Fusible Link Blowing after Lean Burn Conversion

After inspecting under the dash for broken connections and coming up short I went back to wiring diagram and noticed the ignition switch runs through the Oil Pressure Gauge pigtail which reminded me I had tried to move it out of the way when tightening the distributor the first reinstall.
The top of the oil pressure sender is the gage wire connection.
I'm guessing that the three prong is a safety switch for electric choke or other stuff. I would not think it would be the J1 (power feed to switch) but a branch of the J2 (Run) circuit.
