S-afc Ii?

[BuGS]

Two questions:

Is this for a GTX?

or

Is this for a Turbo'd BP?

[Fritz360]

Its for a gtx swaped into a 93 escort gt, with the escort ecu.

It will work. Find a FSM and find the correct wires to splice. I know the VAF wire is red.

[mikeflys1]

The white wire is the tach signal wire.......Thats two.

[elscotto80]

um, no its blue with a yellow stripe.

[BuGS]

Red Wire - Power
Green Wire - RPM Signal
Gray Wire - Throttle Signal
Brown Wire - Ground
Black Wire - Ground
Yellow Wire - Air Flow Signal Output
White Wire - Air Flow Signal Input
Blue Wire - used for 300ZX
______________________________
Red Wire - 12v Source
Green Wire - 2E
Gray Wire - 2L
Brown Wire - 2C(Closer to ECU)
Black Wire - 2C(1cm Away From Black Wire)
Yellow Wire - 2O(Wire Coming From ECU)
White Wire - 2O(Wire Coming From Harness)
Blue Wire - 2N(Reads 02 Voltage)
______________________________
Green Wire - 2E - White
Gray Wire - 2L - Light Green with White Stripe
Brown Wire - 2C - Black with Light Green Stripe
Black Wire - Same but 1cm Further Away
Yellow Wire - 2O - Red
White Wire - 2O - Red

The Red Wire on the S-AFC harness can go to 1B which is a power wire.

If you don't have the service manual this is how the connecters are arranged:

2Y 2W 2U 2S 2Q 2O 2M 2K 2I 2G 2E 2C 2A
2Z 2X 2V 2T 2R 2P 2N 2L 2J 2H 2F 2D 2B

1U 1S 1Q 1O 1M 1K 1I 1G 1E 1C 1A
1V 1T 1R 1P 1N 1L 1J 1H 1F 1D 1B

Plug 1 is closer to the firewall while plug 2 is closer to the center console.

DISCLAIMER: In no way am I responsible for your screw up. If you have any doubts, you should consult your genuine Mazda shop manual or have your Mazda dealer photocopy the appropriate pages from the wiring manual. Once wired up, you will need to tune your car. I can offer tips but again, it is your ass. This device will either help your car or blow your engine up, what you do will result in one of those outcomes. Choose wisely.

Since you have a 4 wire use the 4th wire from the TPS for the SAFC II.

um, no its blue with a yellow stripe.

Yes it is.......if you only want to read 1/4 of the actual rpm.


The ignition system uses two diffrent blue/yellow wires. One is the negative coil/tach wire and the one going to the computer is the Cam Position Sensor wire. If you use that one you'd have to set the afc to a "1 cylinder" to get the tach to work right.

[nolig2278]

I have my safc2 connected to 2g yellow/blue and I set for 1 cyl to get correct reading.

My 2e is not white as mentioned above but is purple/black on my gtx cu is tee any benefit to switching to this wire to get the tac signal.

which of these wires should feed the gauge cluster for mx3 tach?

the safc has no readouts for 02 so why would the blue safc2 wire be connected, or am i confused.

thanks
