Not saying that what your planning to do is correct, but you can ID the wires by the numbers molded into the harness connector that's attached to the ICRM. Disconnect the harness from the ICRM to be able to see what your doing.

Did your IRCM go bad and you are trying to splice around it?

Was gonna say, I picked up my IRCM of off ebay from Van Buren parts for 30 bucks. Popped it in and it worked great.

cut the IRCM wire #14 and splice the IRCM side into the # 17 wire.

Pin 14 (tan/orange) - Signal from EEC to IRCM for low speed fan
Pin 17 (green) - Signal from EEC to IRCM for high sped fan.

The position matters...I'm just trying to help you locate the wire by color if you can't find it by the number on the harness.

David

PS: I think you are reading the wrong row of numbers, or you aren't on the correct harness. The IRCM is located behind the passenger side headlight, forward of the air cleaner box.

get a test probe or multi meter, and check the suspect wire during normal fan operation. Should tell you something.

Since the IRCM gets activation via ground signals, you could also cut the suspect wire, and ground the ircm side. If the fan kicks, jackpot. Lil risky, but it will work none the less.

Cutting and splicing like you are talking about should only be done as a temporary measure. Running the low speed fan all the time is not a good thing because it could stop the car from getting to a proper operating temperature and you could damage the motor with excessive fuel enrichment. Also, there is a reason for the computer shutting the fan off above speeds of 45mph, because the fan becomes a restriction to air flow above those speeds and you'll end up running hotter.

If your car is over heating then get it fixed properly. If you get a chip installed and put a 180 tstat in the car and everything is working as it should even on the hottest days the temp shouldn't go over 200F

Fraser just said what I've been wanting to say sine I saw this thread.

I did exactly what he mentioned (180 t-stat and a chip) and my temp gauge never even touches the "N". That's the right way to do it.

Where is the best place to get a chip from?

Its a poor mans mod thats been done time and time again. It'll runa lil warmer on the highway than if the fan were operating normally. Doesn't have a negative affect as far as the engine running richer, unless its the dead of winter and 20 below out, might help add some ice. Chips are nice, if you got the $$$ for one, and the time to tune it properly, but a basemap only works so well.

There isn't any wire you can cut and get things working if the IRCM has failed certain ways. Best to disconnect the coolant sensor for the engine (it's right there in the front right (your left if facing the motor) of the intake manifold, right by the fuel rail connectors. If the fan still doesn't come on, well then cutting wires isn't likely to do you any good.

Have you verified that the cooling fan even works?

The answers you are looking for are posted in multiple threads. if you just search on cooling fan ircm you'll find all the info youneed.
