You unplugged the connector at the low pressure cycling switch and jumped the two wires on the connector?
Braided wire connecting two spots but that is gone now. Was that the
diode placed across the two clutch coil wires?
One wire at the clutch coil should have 12 volts the Black wire should be ground.
If you have 12 volts going to the clutch coil and it doesn't engage, measure the resistance of the
clutch coil winding. Should be a couple of ohms. If infinite resistance the coil winding is bad.

to allow 12 volts to get to the clutch coil.
Can you post a picture of the braided wire?
