Looking for an 2002 IS300 Electrical Diagram or ECU pin outs for hook up of an APEXi S-AFC.
Please help if someone has any info. Other wise will have to purchase the dealer book.

Thanks.

For 2002 Manual/Auto:

SAFC -> ECU

Red (+12) -> Black/Orange [Tap] (IGSW - A17)
Green (RPM) -> Black [Tap] (TACH - B16)
Purple (KNOCK) -> White [Tap] (KNK2 - D2)
Gray (THROTTLE) -> White/Red [Tap] (VTA - E25)
Brown (GROUND) -> Brown [Tap Closest to ECU] (MEO1 - C3)
Black (GROUND) -> Brown [Tap 1" Further from ECU] (MEO1 - C3)
Yellow (AIROUT) -> Green/Black [Cut, ECU Side] (VG - C27)
White (AIRIN) -> Green/Black [Cut, Sensor Side] (VG - C27)
Blue (NOT USED)
Pink (NOT USED)
Orange (NOT USED)

To find the wires, each of the major connectors is lettered A - E (A is closest to the front of the car). Count the wires from the bottom-left of the connector (closest to front left wheel) from left to right to get the number. For example, A17 is the on the first connector and is the 17th wire - located at the far right of the second row from the bottom. Verify each position against the color.

I ran the wiring harness through the large hole (covered by a giant rubber grommet) under the clutch cylinder.

Here's the wiring harness coming into the ecu box.


ECU connectors labelled for easy identification.


Note the how the two ground wires are connected 1" apart and in what order.

Above is for a SAFC-II Wiring but you could also use it to wire up a SAFC, the only difference is that it wont have the Purple (KNOCK) -> White [Tap] (KNK2 - D2).. But please double check. Im not responsible...

Here is a link for anyone that wants to wire up a TBKO Greddy
