Default APEXI SAFC trouble....HELP!

Wirring diagram for the SAFC is T-10a which shows the speed sensor four pins to the left on one of the plugs.....but there is no wire there.....empty pin....do I put a pin there? Also on another post someone said the throttle connect is wrong and is three pins to the left of the air flow pin.....Wheres the aif flow pin? nothing called that on the diagram...said it was a black/red wire, but the black with red stripe wire is the IG power wire on the far left of the ECU or far right on the diagram....whats up??? anyone experts know? also Apexis number on the box is wrong...any one know it?

Why do you need the speed signal? S-AFC shouldn't require you to tap the speed sensor, it's not on the wiring diagram.

Air flow pin is on the wiring diagram under Air Flow Signal. APEXi-usa.com has the diagram in case you feel yours is wrong.

Throttle wire is the one that says THROTTLE SIGNAL.

Do you know how to read the diagram? Not to be mean or anything but does it say THROTTLE SIGNAL right on the diagram? That's the one.

Maybe your diagram doesn't say all those things. What kinda diagram is that?

Obviously you don't know.

The pic you posted is CONNECTION CHART. The T-10a is the WIRING DIAGRAM. Go look at that.

Don't yell. damn you're rude.

If you're asking for help you better listen instead of shouting back everything you don't understand.


And sasha, if you read the japanese on the 3rd pic you posted, it says WRONG WAY TO CONNECT THE GROUND WIRE.

Ok and which wire on the AFC side is the Throttle wire??? Which color, etc? Why would they say hook the SAFC wire here(the throttle pin) and not tell you which wire out of the AFC is the one to hook to that point? Also it was posted before that the throttle placement is wrong.....any one coment on that?

The wiring diagram shows the throttle signal pin but on the connection chart it doesn't say you need that. How many wires are on the harness of the S-AFC? 6? RED GREEN BROWN BLACK YELLOW and WHITE?
