Can my PCM control my 2spd taurus fan?

[nvrenuff]

I am installing the 2 spd Taurus fan in my 92 LX 5.0 and am wiring it up using relays for now. I plan on getting a chip and dyno tune shortly when I get the nitrous re-installed and was talking to the tuner about controlling this new fan. He wasn't positive if it would work, but showed me in the SCT software for this car where you can activate control of a 2 speed fan and supposedly wire the relays to two output pins in the harness. The software allows you to set the on/off temps for each fan speed and the minimum on time etc to prevent cycling. Do these output pins exist on this PCM? Can this be done?

There is only one control pin for a single speed fan.
EDIT: I tried the fan controller and it doesn't work. Don't waste your time and money.

If you are on a limited budget, try this:

It uses a relay to turn the fan on and off, and uses the computer's temp sense to trigger the fan. It isn't adjustable in terms of temp to turn the fan on and off, but it is cheap. All you need is some 10 gauge wire for the fan power & ground, a 30 amp fuse and some 18 gauge wire for the relay coil wiring.

Thanks for the info, I am not on a limited budget so to speak, Uwas just hoping to control both HI and LO speeds from the EEC seeing as the software has the ability and it was going in for a custom tune anyways. If there are not two separate pin outputs however, then obviously the hardware isn't capable. Maybe I'll get the DCC controller if this doesn't work out.

Thanks for the reply and the great info jrichker. I am not a budget so to speak, the car is going in for a custom tune anyhow, and the software looks to be capable of controlling 2 speeds, so I was hoping to utilize that. If it isn't possible to control HI and LO, then maybe I'll look at the DCC controller.
