FLC 120 no crank, new batteries, starter, solenoid

I have a 98 century with a n14. I recently put new batteries, a new starter (mt39) And now I new firewall solenoid. I have a no crank situation that was not there before. I’m not sure if I blew a fuse Or if there’s a relay in the fuse block somewhere related. It cranks right up with a screwdriver on the solenoid or if I send power to the signal wire on the solenoid.
I’m having difficulty tracing from the ignition switch to the signal wire on that solenoid. I’m just not sure where it goes from there and why I’m not getting power through it. I believe the center wire in the ignition switch is the one that sends the power out, but it just doesn’t make it to the signal wire. Does anyone have any ideas? Thank you so much! I’ve been down for a week.

 

I’ll go take one, but I switched from the original MT 42 Direct Drive starter to the newer MT 39 gear reduction. it works perfectly when I cross over the firewall solenoid with a screwdriver or send power through the signal wire.

 

Yes, correct. Full disclosure I did accidentally arc a battery cable during the swap. Other than that everything went really smooth. I just don’t know if there is possibly a smaller relay on the fuse panel or a fuse that could be angry because of that. I did check continuity of every ignition/ECM fuse. I could find

 

no I have not. I have fuses under the passenger dash and then a few more on the wall behind the driver seat
