How to wire a SAFC
Im gonna try my best to help you by keeping it short and simple but to the point.
You will need a wiring diagram FSM or the one that came with the SAFC.
SAFC *******************************ECU
Red wire (IG Power)***** to*** Orange/Blue stripe
Green wire (RPM Signal)** to*** Blue/Black stripe
Grey wire (Throttle Signal)*to***White wire (not same)
Brown wire (Ground 1)*** to***White wire (same)
Black wire (Ground 2)**** to***White wire (same) 1 cm apart Blue wire = Not used
Pink wire = Not used
There is one more wire that isn't used to I think can't remember the color.
NOTE: (ECU MAF signal wire) Cut the Orange wire in half this is the MAF signal wire that will be running through the SAFC.
Yellow wire (MAF Output)* to***Orange wire connect to ECU side
White wire (MAF Input)*** to**Orange wire connect to MAF side
ALL CONNECTIONS ARE DONE AT THE ECU CLOSEST TO THE PIN AS REASONABLE POSSIBLE BUT NOT TO CLOSE MAYBE 2 to 2.5 INCHES AWAY FROM CONNECTOR (LEAVE ROOM FOR EROR).
1) Disconnect your battery.
2) Ground the SAFC now pay attention here because you can cause damage to the unit if grounds are improperly grounded.
a) There are 2 ground wires:
**Brown wire
**and
**Black wire
It is impairitive to connect the Brown wire closest to the ECU followed by the Black wire 1 cm thereafter the Brown wire.
3) Connect the (Red wire) to the appropriate wire on the ECU.
4) Connect the (Green wire) to the appropriate wire on the ECU.
5) Connect the (Grey wire) to the appropriate wire on the ECU.
6) Connect the (Yellow wire) to the appropriate wire on the ECU.
7) Connect the (White wire) to the appropriate wire on the ECU.
8) (Blue wire) is not used.
9) )Pink wire) is not used.
(9) Take your time and do it right.
If you have the manuel refer to that also I just did this because sometimes it easier to understand when broken down in parts.
