i have a 93 rx7 (FD)5 speed that i bought with no engine & no emissions harness.recently,i bought a j-spec automatic engine and also a 94 5 speed emissions harness that i installed already but its down to a few connections that dont match.i have a blue connector that has seven pins on the bottom that should fit into another female six pin plug.im thinking i should have gotten a 93 harness.can anyone give me some help on this.

 

I didn't know there was a difference in 93 & 94 for the harness. I know 95 doesn't have EGR. Isn't the blue connector for the EGR? I don't beleive any year JDM engine had EGR. Maybe you can ask in the Japan section if no one replies with a better answer. If not, you get a bump anyhow.

 

That is correct.

 

Take a pic of the extra connector and post it up. There's a blue connector near where the harness plugs into the ECU that plugs into the dash harness. I think that connector is slightly different between manual and automatic cars. Might want to read up on the manual-automatic swap threads and look at the wiring differences.

From the European workshop manual:

 

There are LOTs of little wiring differences with the JDM cars - particularly with the version I (91-mid 93, VIN FD3S 1000~) cars. There are even differences within production runs - for example the fuel line has THREE separate harnesses for version I - including one that is for the first 70 cars that were produced! And they all have separate prices.

This is why I always ask for a VIN when I put orders in.

Bottom line: mixing and matching electrical bits and pieces from donor cars and half-cuts will always be a headache. For everything else on the car - 90% is interchangeable all they way from 91 to 02.
