For anyone looking to install an SAFC II into a 2gn. I haven't used this myself....I just have it saved to my computer because it's useful, and I was going to get an SAFC before I discovered MegaSquirt.

BUMP

I think I'll check the wiring on my SAFC and see if they're the same.

Just some FYI from experience:
1 - Do not hook up the O2 wire, 4 days worth of internet research all state that if your already using an A/F gauge to monitor the A/F ratio, taping the apex unit into the same lead will cause incorrect readings back to the pcm and cause future problems. If you want to run the apex unit on an O2 sensor, run it on one of its own seperate from the rest of the system

2 - Make sure you run a tach adapter with this unit unless you have another ignition setup that has a tach output you can use for a clean tach signal

3 - Set cylinders to 4 and TPS to the arrow pointing Northeast(up)

As for other settings im still testing with the DRB to get accurate. I tried the Map sensor 5 in and 5 out setting and it caused problems, but 4in/4out and 6in/6out seemed to work fine. But I'll post more info as I find them....

bumping this old thread...
i'm getting ready to install this and this seems to be the best diagram so far but i have one question for everyone, there is a dotted line between the pressure sensor input and output line. Is that an indication there is suppost to be a bridge placed there? please help!

the input wire goes close to the MAP sensor and the output goes closer to the ECU side of the wire so it will go...

MAP-->input-->one foot of wire (i can't remember how much space goes between)-->output wire-->ECU
