1G 90 eclipse gst ecu pinout

[fupkid]

I am looking for a pinout of the 90 gst ecu. I have looked at the one in vfaq but my wire colors do not match. I just realized my car has a 93 ecu and I would like to get the two wires swapped over.

90 pin 6 is green, pin 14 is green/white.
91-94 pin 6 is green/white, pin 14 is green.

my harness doesn't match that.

Check harness with multimeter: 90 turbo stock ECU pin 6 goes to Idle switch and pin 14 to Air flow sensor. 91-94 turbo stock ECU pin 6 goes to Air flow sensor and pin 14 to Idle switch.

there is no wires on my ecu plug that matches the colors you posted

Here is the connector for my ecu where pin 6 and pin 14 should swap. look at the wire colors.

So do what luv2rallye suggested and use a multimeter to check that the wires running to those pins actually go to what they are meant to go to.

1990 ECU Pin 6 = Idle Position Switch = 1991-1994 ECU Pin 14

1990 Turbo ECU Pin 14 = MAF Active Filter Reset (Turbo MAF Pin 1) = 1991-1994 Turbo ECU Pin 6​

Wire colors really don't mean anything aside from making it a billion times easier to identify. All the wires could have black insulation and, if wired correctly, would work fine. Good luck diagnosing anything though.
