    ah you need a 2nd gen ECU pin out...... most of that smaller ECU plug wires will be relocated or just not used.

    there are no pin-outs for the black/white plugs that i have @ least.

      Got JDM GTX Engine... Going to put into EDM '97 323F BA 1.8 n/a model car.

      So seperate of ECU plugs... we got the connectors hooking up engine harness to car harness, which goes to driverside inside fusebox, and also the gauges as it's 2nd gen.

      Therefor Ill be needing ECU pinouts from the JDM GTX as some wires go to dashboard. But also I need to hook up the cables from the black and white plugs to my more modern plugs in the car.

      Now I've already taken of the female connectors of the old n/a engine loom, so I can use them for the actual connection between the looms. But I need to figure out which wire goes into which socket in order for it all the be able to talk.

      So Ill be needing the engine and the black and white plugs. But there is also another plug besides the black and white ones If I'm not mistaken?

        !! For first photo... The main white plug is maybee from another car, but it was used like this. But you can still see the original wires. Only 3 were
        actually doing something. the rest was just 2nd hand taped off connector it seems.


        What are these for? (mind engine has been in 2nd gen car already) But wiring was not done properly.


        JDM GTX wires...



        Here you see the issue... The blue, gray, and white ones are from the 2nd generation mazda 323F... green is ecu and can be overlooked.
        But right top are the GTX wires again... I need to get the black/white/extra wires onto the blue, gray and white plugs.

        Now I've got those actual B/G/W plugs empty now for use with the GTX loom, now I need to work out how to replug the GTX wires into the B/G/W plugs.

        But as in picture one, some go to the ecu, so ill be needing to know which those are also.

        this is the hardest thing of the whole build I tell you...

          why don't you use your existing harness & modify it to work with the GTX motor???? that would save you a huge headache.

            Hi,

            Because of all the sensor mismatching...

              Is the pinout for GTX and GTR the same? Sorry for the newbie question...
              So the GTX and GTR ecu are OBD1 or OBD2?

                You can plug a GTX, GTR, or GT BP ECU to an n/a GT harness and have it run. There are slight differences, but I'm going to let you figure them out since you admited being a newbie, and newbies really should search and read for the info. Gotta be independent at times man, sometimes you won't find the answer unless you look for it.

                I find common questions on CP can go unanswered for a while due to the simple fact that the information is posted all over the place lol and no one likes sounding like a broken record.

                  OK oddly enough I have a question now too! I'm modifying an MX-3 sohc harness with a 4 wire disti pin to run on a GTX setup.

                  I'm not a stranger to doing the 4 wire tps swap, but I haven't ran into this issue yet as this is my first MX-3 harness.

                  Go to move the LG/W (TPS wire) from pin 19, to pin 7....and well there's a minature ground wire taking up pin 7 that ends at a white, 10 pin plug.

                  I'm guessing this has nothing to do with the actual ECU function, and is just a ground for whatever that white plug is used for (chassis?)...but I'm curious as to where I can move this think #7 ground wire on the ECU plug so it will still be a ground wire.

                    where is the white 10 pin plug .. as in it's the mazda common ground flat non-connector type usually found under the coil on the frame rail type ?

                      it's in cabin, here's a few cellphone pics showing what's going on. There are two thin ground wires going from the ECU plug to these cabin/chassis plugs.



                      Jinx linked me with an MX-3 site with information, but for the life of me I cannot find the pin outs lol

                        man I can't find anything saying what the grounds go to lol, I'm wondering if I can just upgrade the ground that goes to the black plug and "t" off that for the white plug??

                          Found the pinouts!

                          2M is "speed sensor" but advises the following
                          ignition switch "on" Approx 4.5V or under 1.5V
                          Idle Approx 4.5V

                          2H is a "ignition switch Canada" constant, Vb

                          Easy fix as the old TPS spot on the ECU plug (2L) is the spot for the GTX ECU's speedometer signal!

                          So anyone who's working on this style of harness just has to swap 2M and 2L wires to correct the pin orientation for the GTX ECU so it seens proper TPS and Speedometer signal...then the obvious 4th wire (LG/R) gets soldered inline with the airflow meters LG/R wire anywhere along the harness.

                          I haven't found any other differences for the B6 sohc, n/a BP, and GTX for pin outs, so that's all she should need.
