i am trying to find a wire diagram that tells me what wire in each plug goes to what. for example, the ecu has three plugs that plug into it. i want to be able to identify each wire inside each of those plugs and what they go to. if anyone has a diagram i would greatly appreciate it. i already tried to find one on yahoo but no luck. if yo go to yahoo, type in 1993-1995 mazda rx7 ecu diagram and it will show exactly what i am talking about, only i need one for the 91 non turbo. thanks!

 

Just search for

Mazda RX-7 Factory Service Manuals

The wiring will be in there.

 

The link to the Factory Service Manual for series five can be found in the FAQ thread on this site. Then download the FUEL AND EMISSIONS section of that manual. Then look at the section called CONTROL UNIT. It has three pages showing the function of each pin on the ECU plugs.
