I suspect youhave the right solenoid. Some years do not use the I terminal (Prestolite Jeeps?), and the OEM solenoids for them just delete it. The service part has the I terminal; when replacing in the OEM harness, you leave it empty.
Looking at the diagram for '76, I'm wrong about the terminal on the bottom of the solenoid. Your Jeep has the NSS breaking the wire between the switch and the solenoid. Your NSS will be closed in park and neutral but not connected to ground. You need to run the wire to the S terminal from the ignition switch, to the NSS wherever it is located, and then to the starter solenoid. The solenoid coil grounds through the bracket of the solenoid.
