Admittedly I inherited this problem with the slim fans (set up to be pushers mounted to the front of the radiator) on my car as they were installed before I bought it. Problem is I don’t think they ever worked and I hadn’t driven the car in stop and go traffic before so I hadn’t noticed any high temps. I noticed while driving in traffic around the holidays the car would heat up to over 200 degrees measured via DSMLink while stopped and the slim fans would not kick on. Luckily one of the stock “puller fans” is still installed and working so it kicks on and keeps the car from fully overheating and temps lower back down when driving of course. However, since only one of the stock fans is installed only about half of the Mishimoto aluminum radiator is seeing airflow at a stop.
I have found these two threads but I am a bit lost as the wire colors don’t match up and one seems to be about splicing into the factory wiring and temp sensor.

The slim fans are no doubt China knock off's but I want to keep them if I can. Please see the photos attached. Here is what I have done so far:
Pink/Red - I have tested the pink (color coded “red”) wire that runs to an inline 30 amp fuse and then to the battery and I am getting power. Fuse is also good.
Yellow - the yellow wire is run up through the firewall into the car and attached to the interior fuse block via a circuit adder w/ a fuse. I believe the idea is that since this fuse block comes alive when the ignition is turned on the fans are only supposed to run when the ignition (and therefore engine) is on (e.g turning the key on send a signal through the yellow wire to the control/relay? I tested the yellow wire at the control box and I have power with the key on and no power with the key off.
Orange/Blue - The fans themselves are wired correctly and will work and the grounds are good. I removed the cover from the relay by accident and I can manually engage a connection that makes the fans turn on. I also sanded the ground spot very good to ensure clean grounding to metal.
Relay – I have just replaced the relay with a brand new relay and the fans still don’t seem to work when the ignition is on.
Grey Wire/Temp Probe – I am thinking there is something wrong here. When investigating how the fans were wired up in the beginning I found this probe was pushed in between the fins on the radiator on in front of the stock fan. In thinking that the stock fan kicked on before the probe got hot enough to trigger the slim fans to turn on, I removed the probe and tried to use a heat gun and boiling water to “trick” it to see if it would kick the fans on. Nothing. I am not sure how this thing works but it is two small wires going to the metal probe so I tried to bypass the probe and connect the two wires together with a butt connector, thinking this would complete the circuit and tell the fans to kick on. Nothing.
Green – finally there is this green “AC/Clutch” wire that is not hooked up? I have no idea what this is for?
Can anyone help me get my fans to work when the ignition is on? The car is not a daily so gas mileage isn’t a big concern. I am also in southern CA where we get 100+ degree temps in the summer and have brutal weekend traffic. I think my preference is to have the fans stay on all of the time when the ignition is on. Or, if easier to wire up - I would be okay with having the fans linked to the coolant temp sensor to kick on as the stock fan does.
Thank you for any help and input!
