Probably the first thing you should do is to take the harnesses and label each of the plugs based on the FSM. Page 50-103 or so is where the engine, emissions and front harnesses start. The FSM shows plug shape and wire color, so you can figure out what you have and dont have, and a picture a page or two before show where in the car they all should end up. Pictures would also help a lot in identifying what everything is



you can find the FSM by googling ["factory service manual" 88 rx7] without the brackets.

That first one looks like the engine harness (or at least thats how its labelled in the FSM). Its located on the left side (drivers side in the US) of the engine bay. It has the battery connections, the main ground (which looks like its been replaced in your case with that red wire), the fuse box, CAS, alternator, and a few sensors on its side of the engine. At least it has those sensors on it on my car, i recognise some of them on yours.



The second pic seems to be the plug that would lead to a different harness, but thats only based on the observation that mazda liked those bulky, 2-row plugs for harness-to-harness connections.

alright i think i have figured out that this is the auto adjust suspension control unit?? would that be right? did the 10 ae have these? thanks again for allt the help

Mr. Midas

It was an option. Does anyone still use AAS? Labeling connectors is a very good idea for the less obvious/unused stuff. Once you determine something to be NC, mark it with a band of red colored tape or something so you don't have to remember it's NC later on.





There should be two heavy gauge wires running from the battery to the starter. The + side should be solid black and have a #8 AWG? wire attached going into the harness.





I can't emagine having to completely rewire a car. My 88' SE came to me with the motor removed and hacked emission and engine harneses. Had to replace the EM harnes because it was so messed up/missing stuff. FYI, halfway through 1987 mazda changed the injectors to high impedence, and thus the connectors were changed and resistor pack removed.



The dashboard has been out for out for a while now as well. Would it help to have some pics of where stuff goes up front? I could prbably borrow a camera...



Good luck! Just think, when you get finnished with this project, you will be a wiring guru able to recal whole diagrams from memory. You'll be doing this stuf in your sleep in no time...(If you aren't already)

whoa, this is not fun stuff, this is why i stopped turning wrenches and took over the computer and pencil pushing side of things, good luck!

10AE didnt have that. you could ADD it if you wanted too, but its not very cool
