Need pics of 65 Valiant heater cables at the box

I think that illustration posted here will help me more than anything. It appears there that the blower motor wires plug into the resistor on the box and the ground wires to the heater tubes and dash screws. Is that correct? Some reason I see those same wires but sticking out the through the firewall. I pulled them out when I put the box back in the car because I thought they plugged in under the hood like my 73 Charger. But looking back at my pre-tear down photos I noticed too there were no wires coming out around the blower motor. Is the illustration correct? Does that plug go to the motor resistor? I do have one terminal with no wire to plug in on my resistor and no extra plug on my dash harness.
