Ok,, since i have only had conversations with 2 people about this issue,,,,, Thank you CGSheen and Bernard,,,,,,, I have taken more time to look into this swap that I am trying.
Per the following 2 diagrams that are electrical for 280zxt and pin out designation and per 300zx eccs there are more than just the infamous fuel pressure relay (FPR, pin 108 and 16) and the coil wires +/- to 34 and 3 and afm/maf differences.
Pin 6 on the z31 eccs says it is for efi main relay. s130 is blank.
Pin 5 on the z31 eccs says it is for ign on, s130 is to fuel pump relay/fuel pump
Pin 20 on the z31 eccs says it is for fuel pump relay, s130 is to eccs analyzer
Pin 27 on the z31 eccs says it is for AFM, s130 is to ISC, EGR, EFI relay.
Pin 24 on the z31 eccs says O2 sensor for N/A, s130 is to the same but(this is not n/a) Should be pin 110 for turbo titania
Pin 22 on the z31 eccs says FICD , s130 is for a/c switch
Pin 35 on the z31 eccs says CAS, s130 EFI relay switch
Pin 34 on the z31 eccs says ign switch, s130 is blank
Pin 108 on the z31 eccs says fuel pump relay, s130 air regulator
So, am I reading this wrong? Looks like you need to.....
pin 6 put in the 280zxt harness and run to the efi.
Pin 5 needs to be to ign on.
Pin 20 i can skip if I am going to run fuel pump with ignition on no relay.
Pin 27 spliced into the maf/afm.
Pin 24 wire needs to be moved to pin 110. Pin 22 skip cause not using that.
Pin 35 i don't know?
Pin 34 install connector run to ign on.
Pin 108 ignore because not using relay same as 20
Above is wrong see link to fsm diagram below for comparison
