Default IAC Pinouts and ECU Color

Do I use PIN 30 on the DB37 connector for the IAC solenoid?
After going through all the Madracki diagrams I'm still not sure which wire to connect to at the ECU for this. Can anyone make better sense of which pin on the DB37 and stock ECU wire i need to use?

On my 94 I believe it is 2w which is Blue-Orange. I will go download the 99 wiring diagrams and look to see if yours if diffrent.

Thanks

Did you use pin 30 on the DB37 connector for the output?

Not sure about the TPS connection either, which wire there?

Well thats the pin I plan on using. I am having other issues with MS right now so I havent gotten it pluged in yet. On the 99 diagram it looks like IAC is either 3m or 3o. It is on page 10 of the wiring diagrams.

Think i figured out the IAC wire.

Not sure about the TPS.
I think on the '99 diagram:
LTGRN/RED will be my +5vREF
GRN/BLK will be signal line
BLK/RED is the ground

That seems right but I am not positive. If I was you I would definately write down everything you figure out. That way you can make a pinout list for the 99 like kags did for the 90. I know as soon as I get my 94 working right I will be doing one for the 94.

Thats the plan. I have a 95% complete excel document with all the pinouts in it.
