Tried searching seems to be down...I went to Apexi's website to get the wiring diagram....all they have is for the orginal SAFC not SAFC2 are all the wires the same....and for Throttle Signal do u use the Throttle Postion Senor PIN 23 or 37 or Throttle Postion Switch PIN 31.....and air flow signal Do u use PIN 54 Mass Air Flow Sensor...or Absolute Pressure Sensor PIN 61...this is for a 4th Gen

thanx a ton.......

 

can u use any of the other grounds for the Brown and Black wire or does it have to be MAF ground

 

It has to be the MAF ground. Why would you want to use another ground.\?

 

You're grounding the S-AFC not the MAF so it can be any ground. I would personally use the ECCS ground (Engine Ground) though, but that's just me.

Pin #'s 25, 32, 108, 116 (Confirm these with the 1998 FSM)

The MAF ground voltage is APPROXIMATELY 0V. I'd just rather be sure with the engine ground.

 

Thats what i was thinking.....I dunno y it would HAVE to be MAF ground...i woudl rather use the ECCS Grounds as well......i got the FSM so i can confirm PIN locations...but i agree with you ur just grounding the SAFC and it doesnt specify in the manual to use ur pressure sensor ground
