            Bump. Not sure if this is correct info. There's still the throttle wire and with my 4 wire conversion I'm guessing that's where I tap for that.

              Hey, here is the wiring for a 92-93 SOHC

              Red Wire - Power
              Green Wire - RPM Signal
              Gray Wire - Throttle Signal
              Brown Wire - Ground
              Black Wire - Ground
              Yellow Wire - Air Flow Signal Output
              White Wire - Air Flow Signal Input
              Blue Wire - used for 300ZX
              ______________________________
              Red Wire - 12v Source
              Green Wire - 2E
              Gray Wire - 2L
              Brown Wire - 2C(Closer to ECU)
              Black Wire - 2C(1cm Away From Black Wire)
              Yellow Wire - 2O(Wire Coming From ECU)
              White Wire - 2O(Wire Coming From Harness)
              Blue Wire - 2N(Reads 02 Voltage)
              ______________________________
              Green Wire - 2E - White
              Gray Wire - 2L - Light Green with White Stripe
              Brown Wire - 2C - Black with Light Green Stripe
              Black Wire - Same but 1cm Further Away
              Yellow Wire - 2O - Red
              White Wire - 2O - Red

              The Red Wire on the S-AFC harness can go to 1B which is a power wire.

              If you don't have the service manual this is how the connecters are arranged:

              2Y 2W 2U 2S 2Q 2O 2M 2K 2I 2G 2E 2C 2A
              2Z 2X 2V 2T 2R 2P 2N 2L 2J 2H 2F 2D 2B

              1U 1S 1Q 1O 1M 1K 1I 1G 1E 1C 1A
              1V 1T 1R 1P 1N 1L 1J 1H 1F 1D 1B

              Plug 1 is closer to the firewall while plug 2 is closer to the center console.

              DISCLAIMER: In no way am I responsible for your screw up. If you have any doubts, you should consult your genuine Mazda shop manual or have your Mazda dealer photocopy the appropriate pages from the wiring manual. Once wired up, you will need to tune your car. I can offer tips but again, it is your a--. This device will either help your car or blow your engine up, what you do will result in one of those outcomes. Choose wisely.

              And Turpro owes me 2 hrs of sleep... I couldn't get back to sleep!!!

                  Yeah I have the work phone because I am on call incase someone has an electrical issue, and then I use my phone as my alarm clock... sometimes it wakes me up early when People on the East coast forget I live on the West Coast!!!
