for those of u who have managed to work it out :starwars:)

im looking at the english safc.pdf from apexi...

and looking at the safc2 manuals in jap...

and too be honest.. i have nfi

are the wires in same color configuration as before?

there are an additional 2 more....

is it possible to just wire it up as per safc1 diagrams..

and guess work the others? or is that bad for the ecu health? im working on the assumption here that they still are still color coded the same way..

yellow - air out

white - air in

brown - ground

red - power

green - rpm

pink - ?

orange - ?

purple - ?

blue - ?

grey - ground ?

by the looks of things the ground has now moved to the last pin.. near teh IG power?

that leaves the last 4 connectors to the 2nd and 3rd pins looking left to right on the n4-a diagram..

perhaps better still... for a 93 series 1 r33... how to? :)

cheers

Hey dude, i also have an AFC-2... your in luck aswell... i spent hours friggen translating the colors of the wires to match the diagram in the manual... most of the wires are the same colors and have same jobs as the previous SAFC when translated they are...

Red = IG power

Green = RPM signal

Brown = Ground

Black = Ground

Grey = Throttle

Purple = Knock sensor?

Blue = Used for twin turbo set ups with the extra yellow "Y" shaped wire provided, where there is two AFM signals that must be intercepted

Yelow = Air flow/Pressure signal OUTPUT

White = Air flow/Pressure signal INPUT

*Orange = Sustitute Air flow/Pressure signal

*Pink = Sustitute Air flow/Pressure signal

****Not sure what these are used for**** (possibly non turbo set up? Not sure.

K now to use these colors... from left to right on the N4a R33 GTS-t ECU diagram i have narried it down to:

1) Green

2) Purple (check ECU for empty pin cos it can be either of the two pins

3) Air flow wires (white and yellow)

4) Grey

5) Red

6) Ground (grey and black)

Only thing i can't work out is what the pink & orange wires are for... i know the blue is used for twin turbo set ups where there is two air flow/pressure signals due to dual air flow meters, but the orange and pink wires don't seem to come up... i think they are used for non turbo aplications maybe?

Also the only thing i have not worked out is why there is two possible wiring diagrams on pages 8 & 9 of the wiring book. The one on page 9 uses the pink and orange wires as the air flow intercept wires where as the diagram on page 8 uses the white and yellow configeration. Not sure why there would be two?

Let me know how u go.

hey there :P

i had a go and wiring this sucker up today...

The MAF(Hot wire type) and AFM(flap door type) use a voltage signal from the meter to the ECU.

The Karman type sends a frequnecy.

My guess it that White and yellow are for most of us.

The Pink & Orange are for the Kar/Vortex guys.

Damn i wish took i Japanese in 2nd'ry skool :)

a round about process but one way is to copy out the acrobat text and paste it on to the altavista language translator

http://babelfish.altavista.com/

you will need full version of acrobat and a program to break the encryption on the acrobat file, both are available on the net.

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
