85789, Quick clarification of S-AFC wiring. Posted by eclipse982nrRST, May-09-05 03:20 PM
I got the wiring diagram from the MODS section off the home page but I need a few clarifications before I wire this bad boy toy up. Okay question 1: The two negative wires for the AFC, says this: (-)Brown afc wire --> 10 upper (Black wire ECU side) (-)Black afc wire --> 10 upper (Black wire Source side)
-what is ecu side and what is source side?
second question: says this: MAP IN (white afc wire) --> 36 upper (yellow/black wire engine side) MAP OUT (yellow afc wire) --> 36 upper (yellow/black wire ECU side)
-whats engine side and whats ecu side?
can some one point me in the correct direction so I can wire this up tomorrow please? What/how do I wire these 2 sets of wires? Thanks in advance guys!

You solder both to the same wire for the SAFC wires. 2 goes to the engine ground 2 to the MAP
When it says the ECU side, it means this is the one should solder closest to the ECU. This means the same for the MAP.
The other gets soldered like a 1/2" from it, farther from the ECU or the MAP.

ah so engine side and ecu side means closest to ecu and source side means closer to the actual signal, like you said 1/2" or so away. okay cool cuz it said something about cutting the map wire on the home page of the boards. btw, i am not soldering cuz my gun is broke, im going to heat skrink :)

If you dont solder, you might be paying for it later on.
I fried 2 ECU's before I figured out the problem. Go buy a solder gun and do it right the first time. Save yourself problem diagnosing in the future.

Basically what you're doing is interrupting the MAP signal to the ECU. Those two wires hook onto each end of this single wire. To ECU connects to the part of the wire that you cut that is connected to the ECU. To the MAP connects to the wire that is coming from the sensor to the ECU, however now it's going to the SAFC.

oh so i actually cut the MAP wire in half then? ah okay.
