Hey Guys I'm struggling understanding how to wire up my HSD manual tool release and was looking if someone can help me figure this out!






So im confused how to hook up the wires on the pigtail. I understand pin 7 wire will go to a 24v power supply, I dont understand what I connect the pin 8 wire to? Is "P" something I have to add or something that was possibly on the old Controller board or something inside the spindle itself? Andddd I dont understand "C" and "E" lol Any help would be greatly appreciate!

Thanks
