SAFC ASSISTANCE

[Tx-Sx-FS]

its a dohc 92, just need a hand drawing on piece of paper scanned and sent to my email showing where each wire needs to be spliced and soldered and wire color matches...thanks and appreciate the help, ive searched and cant find the N3-B diagram or Apexi's diagram...this is last part to my project completion.

does this help? I wish I remembered which one I used.

i have that part, i need a pic of where safc wires tap into ecu harness...ie, ecu then lines (mainly pinouts 16 and 17 are MAF and MAF ground) ...which colors from safc harness goto these?? im pretty sure its like this though:

Ecu = Safc

#3 Tach (Yellow/Red) = Green#16 MAF (White)= Yellow???#17 MAF Ground (Black) = White???#20 TPS (White) = Gray#47 Grounds (Black/White) = Red#27 Knock (White) = Pink or Purple ----does SAFC 1 have this wire function??

if not: then on my harness ill have excess wires, like pink orange and blue (any functions for these??)...can some explain where the white and yellow get spliced and where they meet back up??? i wanna put my 2 cents on this but cant seem to word it right so someone with experience on the MAFS part let me know.

This is a open source version of MS office, and in my opinion a lot better.

it's actually so good MS copied its new design and used it in Microsoft Office 2007.

i dont need the wire pin outs or number...i need help with the actual wiring...re-read my secon post cuz i edited it..to what im actually needind to know..thanks for the quick replies guys...much appreciated.

So you need ot know which wire from the safc goes to what wire on the ecu pinout. I know purple is knock, black and brown are gorund, red is power, white is af in yellow airflow out? Might have those backwards but is that what you need?

[Florida240sx]

Very good write-up only thing missing is for the Safc II is the purple is knock sensor. OTher thna that safc I and 2 are the same.http://www.tylermerrick.com/co..._id=4

hey, that was the best pic, help so far, but everyone has helped....but the yellow wire taped into what white wire--the #16 pin?? ...and the white wire goes to what other wire-- pin number?? ...just basically a break down of the the white and yellow wires, the pics always show a splice in the white and continues to ecu in yellow and but does show where the white goes in and comes out yellow

[Tx-Sx-FS]

okay, ive figured that u sent the yellow to ecu pin #16 (white from ecu plug), but the white from SAFC plug goes to what other whtie wire to ecu plug?? need that pinout # and ill be straight and confident in wiring it.

CLearer Pic: What ecu pin # is the bottom white wre goto??

Not So Clear Pic:

u doin a great job, can u look at my other posts and possibly help on those (2 other posts)

I got your email dude and replyed back but incase you check here first, the SAFC wires (Yellow & White) attach to the same ecu wire. You have to cut your air flow ecu wire, then attach the Yellow SAFC to the air flow wire on the harness side and the White SAFC to the air flow wire ecu side. The SAFC sends a false signal to the ecu saying all is fine at the same time controlls your air/fuel ratios via the NE Points.

It's all explained in the email along with your other questions. If you need anything else, feel free to ask. I may not have my 240sx KA-T anymore but I don't mind helping anyone out (if I can) if they need it.

Easy bro

Got that backwars. Yellow to ECUWhite to harness
