I've spent the last few days scouring the internet looking for wiring diagrams for my car. What I have is the drivetrain and wiring from a 1988 NA Convertible RX7. I plan on putting these into a new car, and as such I need to go through the harness and remove extraneous connectors without removing anything important.

I've found the FSMs that are floating around both here and on several other sites. The 1988 manuals have a great section at the end showing each harness, and the connectors on each. The only problem is that they are for a turbo car with ABS. As such my harness doesn't have all the connectors shown in the diagram, and the diagram doesn't have some of the connectors my harness has.

So I'm looking to find out if accurate NA diagrams exist for this year, or will I have to continue working through the differences myself? Do the Haynes manuals have decent diagrams worth purchasing? Do one of the other year manuals accurately depict the NA harness I have?

Thank you sir. That at least answers my question about the Haynes.

Looks like what I've found is what is available. I'll start comparing the 1991 manual to the 1988 and see what other information I can pull together.

 

The harnesses are different between the 86-88 and 89-91.
The 89-91 incorporates the electronic oil metering system (OMP) as the earlier 86-88 had mechanical oil metering.
86-87.5 had a resistor pack for the fuel injectors while the 88 model had no resistor pack connector on the harness.
The S4 used the N326 0r 327 ECU which is basically the same and looked for HI impedance injectors(LO with resistor or HI with NO resistor)
