So i have two blitz machines both with somewhat similar, yet different issues.

Machine 1:

Everything seems to work but the joysticks.

Run, turbo, start and jump for all four players will register on the test screen but for the life of me none of the joysticks register anything. Zip, zero, nada.

Yes, the dip is set for 49 ways, so its not that. I believe the issue to be how my i40 is plugged in and the fuse wires and their specific order.

Machine 2:

Similar to machine one, but on this machine the Player 1 & 2 buttons all work fine, but player 3 & 4 buttons do not register. Also none of the four joysticks work here either. Once again i have confirmed the 49 way dip switch on this machine as well. But once again the fuses and i40 plugs might be the issue?

Im pulling my hair out here guys. Any helpful suggestions???
 
Dip screens for both machines.

This is my wiring for machine #1

Pink represents the red wires
Black for black wires.

Like this doesn't seem super difficult. One connect has four wires. The others have two so its easy to match up... the fuses test positive for continuity so they arent blown...

What am i missing?
