10 min fan mod
I have seen many fan mods, but I have not seen the one I just perform, so if it is a duplicate sorry.
On the pass. side fan look for the group of 4 wires going to the fan. There should be 4. take the blue one and connect a wire to this one run it through the firewall and connect to a fuse that turns on with the ignition ( I used the lighter fuse location) Turn on the ignition and the fans turn on. They will run as long as you have the key on. You can also add a switch if you want to control it.
Has anyone every used this one? If not it is alot easier than the ones I have see posted before.
Hope this helps!

I think that the gounding trick behind the passenger kick pannel may be easier, and more effective. The ignition on, fan on trick sounds good for hot places, but in cold climates I think that it would keep your engine from getting to running temp quickly.

The box fan sounds like a great idea!
"The ignition on, fan on trick sounds good for hot places, but in cold climates I think that it would keep your engine from getting to running temp quickly."
I am in TEXAS which means hot and I have a FMIC. If you don't want them to run all the time all you do is install a $2 switch and turn them on when you want them.

Yea its easier to wire the lose
ground wire from the Fans at the
ECU where passenger footpanel is.
And deffinately wire it to a switch ($3 part from
Radioshack). Why would you need fans on
cruising at 80mph??
IMO: I dont think its a good idea to have your
fans on ALL the time. Harder to warm up and
cause early fan failure.

Radiator fans shouldn't really affect warm-up times. Like any even remotely modern car engine, the rx7 is equipped with a thermostat, that doesn't direct coolant to the radiator until it's reached a desired temperature. The thermostat isn't exactly digital though, so it'll be partially open before you've reached it's spec temp, but the effect should be marginal, given that your thermostat is in good condition.
Just my $.02

I was under the impression that fans move less air that your car ingests at speed.. and therefor get in the way and hurt airflow.. better to NOT have them on while you're moving any faster than like 30 mph or so..

Another new way?
I am going to try the ECU grounding thing with a twist.
Rather than have another switch, I am going to wire it to my parking brake switch via a diode (in both handbrake and ECU line) and make sure that on the first point the handbrake is triggering the switch, which is grounding the light so the ECU line is grounded, it is not quite putting any brake force on. So by setting the handbrake slightly 2 minutes before I stop the car I will trigger the fans. And it will be reset automatically with the release of the handbrake.
I'll let you know if it works as I say. IMHO

If you have a 94-95 or a 93 with the fan recall then this will kill your battery cause the fans will stay on the entire time while your parking brake is on, even if your car is off.

I ended up putting a switch on mine, for the 2 days I had them running all the time I saw no difference in the warm up time. To me this one is easier that the ground method, but to each is own.

I haven't done it yet, but I will be. I did the quickie wire grounding of the one by the ECU which doesn't do squat on my car..

Today in Socal is at least close to high 90 deg's, with fan on all the time and Koyo radiator, PFC shows water temp not anytime over 86 deg. C.
I think the fan supplements the air flow at high speed, to what speed I don't know, but for daily driving on freeway it worked for my car to keep the temp down even on the freeway.
