Engine Compartment Harness question

To be honest..........I took it out to the garage and looked at the firewall box..........With whats at the end of the harness theres no way it will fit let alone match up to the prongs that are there and that arent?????????Im puzzled considering i was told the car was running at one time ...well approx. a year before i got it. Hmmmmmmmmmmm:scratch:
