Replacement A/c clutch #47564 wiring

There are multiple applications for this part Does that mean I can omit the black wire with the resistor or just ground it to the engine or compressor

The clutch ‘field coil’ only needs two wires to engage the clutch plate - power and ground. Maybe you have a friend that’s pretty savvy when it comes to auto repair that’ll help out. Also make sure there isn’t another problem that caused compressor clutch failure!

That’s what I thought and was wondering if it was ok to cut off the black wire coming from the resistor I’m not sure why 2 ground wires were necessary and what the purpose of a ground wire was coming from the power source with a resistor
