What colour coated wires, of the ECU, get tapped In the S-AFC?
On an 88 GXL. I know these wires, of the S-AFC are used. But for confimation I want to know where these wires are being tapped Into on the ECU.
Red: power
Black: ground
Brown : ground
Green: RPM
Yellow: Air flow meter output (ECU side)
White: Air flow meter input (AFM side)
Grey: TPS (throttle)

Just read the wiring diagrams from A'PEXi and you shoudol be fine. That is what I used to install mine. I also have a write-up on my site on installing it, It is really easy to do. A'PEXi has all of the documentation to do it.

The throttle position wire is in the middle plug, pin 2G, and the color should be green/red.
The ground wire is in the middle plug, pin 2C, and should be black(brown/black if its a 86-87 model)
The air flow signal is in the middle plug, pin 2E, and the color is green/blue
The rpm signal is in the right plug, pin 1X, and the color is blue/yellow.
Notice how the the plugs are labled? They start on the top right of the plug calling that pin A, and the one below it B, and keep on doing that from right to left, up and down.

Red: power - did not mention
Black: ground - mentioned
Brown : ground - mentioned
Green: RPM -mentioned
Yellow: Air flow meter output (ECU side) - Not sure which
White: Air flow meter input (AFM side) of the 2 u mean?
Grey: TPS (throttle)- mentioned

Power is the black/yellow in the far left plug. Top row, far left.
Ground is anywhere you want. To the ECU bolts is fine.
AFM........Middle plug. Third wire over from the right. Top row. Green/blue. I THINK they want you to cut that wire about four inches back from the plug. Now its two wires. Both green/blue. One is going to the ECU. One is coming/going to the afm.
I've never done one of these, so take it for what its worth.

ground has to be on the ecu wire... read the instructions.... there are more then one wire with the same color. you need to go by wire placement. which is why it comes with a diagram...
both grounds go on the same wire. an inch apart. you must put them in the right order, closer to the ecu. read the dirrections or writeups above...

Thanks guys once again. I found It difficult Interpreting how the the plugs are labled. i.e They start on the top right of the plug calling that pin A, and the one below it B, and keep on doing that from right to left, up and down.
