electrical issues with the 67 fish

Thanks for the reply. I grounded the NSS spade and still no start. I also measured the voltage of the ignition switch start wire and only reading 9,6 volts. The battery reads 12. I also put my old relay back in which is correct and still no luck. All was good until I pulled the instrumnet cluster so it must be a ground or something else. I checked the ignition switch connection as well and it seems fine. the key will turn the car off after I jump start it at the relay as well. I am stuck!
