Still trying to figure out barely running 75 1.8 L jet blues

Looked at relay board and found missing rear window defogger fuse which is no big deal but also saw missing power supply relay fuse ???? Unknown what this is for. Then unknown yellow wire.

Not sure if you fixed your electrical issues yet, but even if you did, try this. Remove your relay board and look at the bottom. The boards were sealed with a tar like compound that seems to melt and decay with heat and age, especially below the voltage regulator. If it is degraded, the connectors beneath it will push down when the VR is inserted and result in poor or no contact. Good luck!
