1976 280Z with 1977 engine wiring harness- got questions.

I have both wiring diagrams but I cannot really afford to print and laminate the '77 harness so I can compare them both (unemployed and a full time student) ; but can anyone tell me the differences between the '76 engine harness and the '77? I have it installed but I am not getting signal to the fuel pump. I heard there were differences with the MAF sensor that link directly to the fuel pump. any one have any info?

Thanks,

Randy
