Did some searching on this topic.I've got an safc II and I'm trying to wire it into a 1jz supra with a dr.tweak pnp harness running a JDM 2J aristo ECU.

I just checked the apexi site which seemed to be down for some reason....

After some digging I found this diagram someone had made for a JZS147 Aristo:

^^^ This is a little confusing & I worked out the following by looking at it:

Green- RPM signal
Purple- Knock sensor(most people don't use this apparently)
Grey- TPS
Black- Ground
Brown- Ground
Red- Ignition power

now this leaves me with 5 wires (orange,pink,blue yellow & white)
my questions are:

-which wire would I use for a pressure signal from the map?
-what other wires would be used in the installation or have I covered all the bases?
-since there are two ground wires do I splice the black wire into the brown wire and then into the ground wire on the ecu side?

on a side note the previous owner stated the car had a 2j soarer ecu but that doesn't seem possible since soarers never came with 2jzgte's (correct me if I'm wrong)

had a brain fart there for a moment...it's more simple than i thought.

finally got a pdf of the manual and actually looked at some of the installation notes.

white is pressure signal in to the afc unit, and then yellow is pressure signal out.

brown/black ground wires don't get spliced into one another. but get spliced individually into the ground wire on the ecu side.
but they get wired so the brown wire is closer to the ecu.

orange,pink, & blue remain unused.
